Genetically Engineered Dinosaurs Amok

The first sequel to the massive success of Jurassic Park where Steven Spielberg returns to direct with a script that seems a mishmash of loose ends that only weakly rehashes the original

H.P. Lovecraft Adaptation/Creatures Beneath the Graveyard

Charles and Albert Band had a success with the H.P. Lovecraft adapted Re-Animator; their attempt to replicate that with another Lovecraft story is lacking Stuart Gordon’s splattery black humour

Mad Doctor of Blood Island (1969)

Rating: ★★
Filipino Exploitation/Mad Scientist/Monster Amok

The original Filipino exploitation classic, this pumps the 1940s mad scientist film up with gore, toplessness and tropical locations. A reasonable hit but surprisingly dull and sedate despite

Wilderness Survival Reality TV Star Encounters a Creature

The amusing idea of a mimicry of a Bear Grylls-type wilderness survival reality show – but with the addition of a monster.

Meg 2: The Trench (2023)

Meg 2 The Trench (2023) poster
Rating: ★★★
Giant Prehistoric Killer Sharks

The sequel to the Jason Statham starring killer shark film, bigger and more over the top than before. The surprise is seeing cult director Ben Wheatley turning to making a big, dumb film

Mega Piranha (2010)

Mega Piranha (2010) poster
Rating: ★★½
Giant Fish Amok

If you could take it seriously, Mega Piranha would be a strong contender for a bad movie; however, its awareness of its own absurd shortcomings becomes its saving grace. The sight of giant piranha skipping down rivers and impaling themselves in the sides of buildings has an appealing delirium

Mega Python vs. Gatoroid (2011)

Mega Python vs Gatoroid (2011) poster
Rating: ★★★
Giant Animals Amok

The Asylum had hits with Mega Python vs Giant Shark and Mega Piranha, both featuring former teen pop stars Debbie Gibson and Tiffany as the leads. This pits both Tiffany and Debbie together in an epic bitch-fight against the backdrop of clashing giant animals with rather entertaining results

Mega Shark vs. Crocosaurus (2010)

Mega Shark vs. Crocosaurus (2010) poster
Rating: ★½
Giant Monsters

The first sequel to The Asylum’s Mega Shark vs Giant Octopus and marginally a better film. This is less sparing with the cheap effects, while in every other regard it plants tongue-in-cheek and tries to make a virtue out of the sheer ridiculousness of the action

Mega Shark vs Giant Octopus (2009)

Mega Shark vs Giant Octopus (2009) poster
Rating:
Giant Monsters

The Asylum’s first venture into the gonzo shark movie that would spin off a series of sequels and culminate in the Sharknado phenomenon. Despite one of the great attention grabbing titles of all time, this is an unmemorable affair

Mega Shark vs Mecha Shark (2014)

Mega Shark vs Mecha Shark (2014) poster
Rating: ★★
Giant Shark vs Giant Robot Shark

Third in The Asylum’s series of Mega Shark films where they borrow the Godzilla series’ idea of Mecha-Godzilla and pit the Mega Shark against a robot copy of itself. Here the Mega Shark series is starting to approach the entertaining silliness of their Sharknado films but still flounder amid tatty effects

Metamorphosis (1990)

Metamorphosis (1990) poster
Rating:
Mutating Scientist

An Italian exploitation film intended to take advantage of the 80s makeup effects revolution of the day as a scientist injects himself with an untested serum and transforms into a monster

The Millennium Bug (2011)

The Millennium Bug (2011) poster
Rating:
Backwoods Brutality/Monster Movie

The Y2K Problem was a now largely forgotten social apocalypse that never happened so why someone is making a film about it now is a scratch of the head. This is a Backwoods Brutality film that abruptly jumps tracks to become a monster movie

The Mist (2007)

The Mist (2007) poster
Rating: ★★★★
Creatures in the Fog/Stephen King Adaptation

Frank Darabont delivers one of the best Stephen King adaptations where the story of people at siege in a supermarket from unseen creatures in a mystery fog outside becomes a study in fear and prejudice. With one of the great unforgettable endings

Mongolian Death Worm (2010)

Mongolian Death Worm (2010) poster
Rating:
Giant Worms

Another low-budget monster movie for the Syfy Channel. Between Sean Patrick Flanery’s unconvincing adventurer hero and the filmmaker’s failure to even vaguely approximate what Mongolia or its locals look like, this quickly slides down into a tatty, indifferently made copy of Tremors

The Monolith Monsters (1957)

The Monolith Monsters (1957) poster
Rating: ★★★
Monstrous Alien Rock Formations

A very underrated 1950s sf film … Neither quite alien invader film nor monster movie, it features some of the most original creatures of the era – rocks from a meteorite that grow into massive geodes that devour everything in their path – and eerily atmospheric direction

Monster (1979)

Monster (1979) poster
Rating:
Monster Movie

Obscure 1970s film about a monster emerging from a Colombian lake. The film taps a bunch of subplots and cliche themes but fails to make any of them even remotely interesting. The entire show though is plunged into bad movie stakes by the emergence of the ridiculous monster at the end

The Monster (2016)

The Monster (2016) poster
Rating: ★★★½
Roadside Monster Movie

A monster movie that consists of a mother and daughter cowering in a crashed car on a remote stretch of road. The effectiveness of the film comes in the incredibly raw emotional groundwork laid in the first half

Monster Brawl (2011)

Monster Brawl (2011) poster
Rating:
Wrestling Match Between Famous Monsters

This has the mildly amusing idea of taking the idea of films like Dracula vs Frankenstein et al one step further and actually pitting various classic monsters against one another in a wrestling match. Beyond its mimicry of televised wrestling though, there is almost nothing else to the film

The Monster Club (1980)

The Monster Club (1980) poster
Rating: ★★
Horror Anthology

Following the collapse of Amicus Films, producer Milton Subotsky went on on his own to make this horror anthology, the bread and butter of Amicus in their heyday. Though he brings in some major horror names – Vincent Price, John Carradine – the jokey tone failed to find any success

Monster from Green Hell (1957)

Monster from Green Hell (1957) poster
Rating:
Giant Mutated Wasps Amok

Possibly the worst film to be made out of the 1950s giant bug cycle concerning giant wasps marauding in Africa. All the dramatic scenes are composed of scenes cannibalised from other adventure films, while the effects have a shoddiness that frequently reduces you to laughter

Monster from the Surf (1965)

Monster from the Surf (1965) poster
Rating:
Surfers vs Sea Monster

Another Z movie attempt to join the 1960s beach party movie fad with the additions of monsters that ends up being fairly ridiculous on all counts

Monster in the Closet (1986)

Monster in the Closet (1986) poster
Rating: ★★
Monster Movie Parody

Monster movie parody that spoofs a number of classic films, including King Kong where it takes the title literally and the monster makes off with the hero giving the film a certain LGBT community relevance in its day. Contains quite an impressive cast list, including featuring both Paul Walker and singer Fergie as kids

The Monster of Piedras Blancas (1959)

The Monster of Piedras Blancas (1959) poster
Rating: ★★
Prehistoric Monster

Minor and largely undistinguished 1950s monster movie. The monster is a blatant copy of The Creature of the Black Lagoon and similarly has biologically improbable designs on the heroine. Routine on all accounts

The Monster Squad (1987)

The Monster Squad (1987) poster
Rating: ★★★
Kids vs the Famous Monsters

Rather charming effort where the Famous Monsters – Dracula, the Frankenstein Monster, the Wolf Man, The Mummy, The Creature – are revived and pitted against a group of kids. The film has a great deal of affection for the originals and the encounters are delightful

Monster Zero (1965)

Monster Zero (1965) poster
Rating: ★★★
Japanese Monster Bash/Space Opera

The sixth Godzilla film, the first where the series combines elements of space opera – a typical entry of the era and colourfully entertaining about it too

El Monstro del Mar! (2010)

El Monstro del Mar! (2010) poster
Rating: ★★★
Grindhouse Homage/Monster Movie

Australian exploitation homage that is like a collision between Faster Pussycat, Kill! Kill! and a monster movie. Low-budget but this has an authentic recapturing of the spirit of trash cinema

Mortuary (2005)

Mortuary (2005) poster
Rating:
Creature in the Crypt/Body Snatchers

Another effort in the sad slide into shabby amateurishness that marked that latter years of Tobe Hooper’s career, a muddled effort set around a mortuary involving body-snatching fungus and deformed relatives in the crawlspaces

Mosquito (1995)

Mosquito (1995) poster
Rating: ★★
Giant Insects

A ridiculously stupid giant bug film, albeit not unentertainingly so. This is a monster movie that has been premised solely on the provision of ridiculous creature effects every few minutes and very little else that one can take seriously beyond that

Night Fright (1967)

Night Fright (1967) poster
Rating: ½
Alien Monster

An incredibly dreary film about an alien monster menacing a small town. The alien invasion cinema equivalent of watching paint dry. Unseen during its original release, it was then resurrected in the VHS era as an E.T. copy called E.T.n – The Extra-Terrestrial Nasty

Nightbreed (1990)

Nightbreed (1990) poster
Rating: ★★
Secret City of Monsters

The second directorial film from Clive Barker is a hugely ambitious work concerning the discovery of a city of monsters – containing some extraordinary makeup creations – but proved a box-office flop

Otesanek (2000)

Otesanek (2000) poster
Rating: ★★★★
Wooden Log-Baby Monster/Gonzo Surrealism

Hilarious Jan Svankmajer film about a mother who decides to treat a log as a child. Full of blackly funny humour before transforming into a macabre monster movie

Pacific Rim (2013)

Pacific Rim (2013) poster
Rating: ★★★½
Giant Mecha Robots vs Giant Monsters

Giant mecha robots beating the crap out of giant monsters – what’s not to like? In comparison to the Transformers films, Guillermo Del Toro looks to find the soul of the robot jock – in essence, Transformers for grown-ups

Pacific Rim: Uprising (2018)

Rating: ★★
Giant Mecha Robots

Pacific Rim wasn’t Guillermo Del Toro’s best film but it was a fun attempt to imagine giant Japanese mecha robots battling giant monsters. This is a sequel but without Del Toro it is reduced to no more than one of Michael Bay’s Transformers films

Phantoms (1998)

Phantoms (1998) poster
Rating: ★★★★
Evil Force Takes Over a Small Town/Dean R. Koontz Adaptation

One of the best and most underrated Dean R. Koontz adaptations, which creates eerie atmosphere out a town where the residents have disappeared due to what is revealed as a uniquely different creature

Piranha II: Flying Killers (1981)

Piranha II: Flying Killers (1981) poster
Rating:
Killer Fish

The film that James Cameron would prefer we forget about. A nominal sequel to Joe Dante’s enjoyable tongue-in-cheek Piranha, this misses that film’s sense of humour and lets the show sink amid absurd effects

Piranhaconda (2012)

Piranhaconda (2012) poster
Rating:
Giant Hybrid Snake

Amid the spate of deliberately ridiculous monster movies of the 2010s, we have also seen a fad for absurd hybrid creatures. In actuality, the piranhaconda is just a giant snake – and served by some incredibly bad effects in this negligible effort from B-budget hack Jim Wynorski

Possession (1981)

Possession (1981) poster
Rating:
Marriage Breakdown/Surrealism/Monsters

Bafflingly surreal film from Andrzej Zulawski in which Isabelle Adjani gives birth to a tentacled monster in a subway. Nobody has any idea what the film is about but it has become a cult work since

Prey (2004)

Australian Monster Movie

Obscure Australian film about people being hunted by a mythical creature known as The Yowie

Project: Metalbeast (1994)

Project: Metalbeast (1994) poster
Rating: ★★
Cyborg Werewolf

Typical 1990s video-released effort that stands out by dint of a far-out idea – a cyborg werewolf – even if in the end the film does nothing with it and everything only boils down to a standard monster movie that takes everything from the Alien playbook

The Pyramid (2014)

The Pyramid (2014) poster
Rating: ★★½
Sinister Forces in an Egyptian Pyramid

A monster movie where the major distinction is that the monster is drawn from Ancient Egyptian mythology and the locale is an unearthed pyramid. The film is too conceptually slim to do much with such an interesting background but it does deliver some solid jumps

The Quatermass Experiment (2005)

The Quatermass Experiment (2005) poster
Rating: ★★★
Mutating Astronaut

A remake of the first Quatermass story conducted as a live broadcast tv movie. Quite a considerable technical achievement considering the limitations and one that works with quite reasonable results

The Quatermass Xperiment (1955)

The Quatermass Xperiment/The Creeping Unknown (1955) poster
Rating: ★★★★
Mutating Astronaut

The first of the Quatermass films and the first major genre hit for Hammer Films. Nigel Kneale creates a literate work of science-fiction horror about a returned astronaut mutating after exposure to an alien fungus

A Quiet Place (2018)

A Quiet Place (2018) poster
Rating: ★★★★
Survivors Unable to Make a Sound in the Aftermath of an Invasion

An uncommonly effective film that takes place in the aftermath of an invasion by creatures with ultra-sensitive hearing where the survivors must maintain an existence that requires not making the slightest sound. Director (also lead actor) John Krasinski uses the set-up to create unbearable tension

A Quiet Place: Day One (2024)

A Quiet Place: Day One (2024) poster
Rating: ★★★
Survivors Unable to Make a Sound in the Midst of an Invasion

The third in the trilogy of A Quiet Place films, this is a prequel that takes us back to the start of the invasion

A Quiet Place Part II (2020)

A Quiet Place Part II (2020) poster
Rating: ★★½
Survivors Unable to Make a Sound in the Aftermath of an Invasion

The first A Quiet Place was No 1 on this site’s Best of 2018 list. John Krasinski still pulls off great set-pieces a second time but reveals the pitfalls of trying to extrude a premise to make a sequel

Raiders of the Lost Shark (2015)

Raiders of the Lost Shark (2015) poster
Rating:
Flying Killer Shark

This is the one of worst films to come out in the gonzo killer shark fad – it is surely the killer shark genre’s equivalent of The Room. The effects hit a level of terribleness not seen since Birdemic, the rest is full of ridiculous continuity gaffes, bad acting and bad dialogue

Rare Exports (2010)

Rare Exports (2010) poster
Rating: ★★½
Discovering the Real Santa Claus/Giant Rampaging Santa

A Finnish film that comes as appealing anathema to the rosy sentiments of most Christmas films – more like a monster movie where Santa is a monster that punishes bad children

Rawhead Rex (1986)

Clive Barker Adaptation/Prehistoric Monster Revived

Early Clive Barker adaptation made just prior to his gaining fame with Hellraiser about a the revival of a monstrous pagan pagan that suffers from shabby treatment and a rubbery monster

Rating: ★★★★
Killer Boar

Russell Mulcahy, a director fresh from success on the early days of MTV, returned to his native Australia to make this extraordinary variant on the Animals Attack film. Mulcahy piles on amazing photography, turning the landscape into something otherwordly

Rebirth of Mothra (1996)

Rebirth of Mothra (1996) poster
Rating: ★★
Japanese Monster Bash

One of the worst among the usually worthwhile Japanese monster movie revivals of the 1990s. Much of the film is played down at an inanely silly children’s movie level, with there only being the requisite mass destruction effects to enliven the show

Rebirth of Mothra II (1997)

Rebirth of Mothra II (1997) poster
Rating: ★★½
Japanese Monster Bash

After their successful revival of Godzilla in the 1990s, Toho revived Mothra for a series of standalone battles, albeit with a very juvenile focus made for children. This was the second and better of the three films

Rectuma (2003)

Rectuma (2003) poster
Rating: ★★★
Giant Rampaging Ass/Bad Taste Parody

The sort of film that might make Troma radioactive green with envy they didn’t make it concerning a giant rampaging ass. Mind-boggling and willing to be stupid and in frequent bad taste

Reeker (2005)

Reeker (2005) poster
Rating: ★★★
Hunted by an Unearthly Creature

An initially low-assumption film that rapidly becomes highly watchable thanks to some way out jumps and creature appearances that propel it into real WTF territory. Where it falters is its arrival a well and truly cliched twist ending but the ride there is undeniably memorable
