Monster movie flops that deserved better
Although monster films like Stephen Sommers’ Deep Rising (1998) and Vincenzo Natali’s Splice (2009) showcased stunning creature effects and bold narrative risks, they grossly underperformed in theaters.
Deep Rising earned only $11.2 million against its $45 million budget, marking a notorious box-office flop, while Splice struggled to find an audience despite its provocative genetic-horror premise.

The Relic
Not to be confused with the 2020 Australian horror film of the same name. The Relic is a ’90s creature feature set in Chicago’s Field Museum. A terrifying beast begins stalking and killing staff. It wears its Alien influence proudly.
What sets it apart is that it is an unforgettable hybrid of mammals and reptiles. The legendary Stan Winston designed it. Thanks to its mix of practical and digital effects, it still holds up today.

Deep Rising
Deep Rising bombed at the box office and flopped with critics when it came out, but it’s built a loyal cult following over the years. It follows hijackers trying to rob a luxury ocean liner, only to run into massive sea monsters.
It’s scary, funny (even if unintentionally), and packed with wild creature effects. It didn’t stand out back then, but it holds up as fun, B-movie horror today.

Night of the Creeps
Surprisingly, James Gunn never cited Night of the Creeps as an influence on Slither, and he says he hadn’t seen it beforehand. Directed by Fred Dekker, this ’80s cult classic features alien slugs crashing a college during pledge week, turning frat guys and co-eds into zombies.
Like Slither, it mixes ’50s sci-fi and ’60s zombie tropes. With a clever script, bold references, and plenty of gooey fun, it remains one of the most entertaining zombie films ever made.

Howl
Many of the best werewolf movies came from the 1980s, and newer ones often struggle to stand out. Howl, a 2015 British horror film, is one of those underrated entries. It didn’t get a theatrical release but quietly premiered at film festivals.
The movie follows train passengers trapped with a vicious werewolf, and the enclosed setting adds real tension. With strong special effects from director Paul Hyett, Howl delivers solid scares and deserves more recognition from horror fans.

The Blob
This 1980s remake of the classic ’50s B-movie gave The Blob a modern twist and dialed up the gore. Made at the height of practical effects, it delivered creative, gruesome deaths courtesy of a roaming pink pile of goo.
Unlike The Fly, it flopped at the box office. A new version has been rumored for years, even with Rob Zombie, but it’s never materialized. So for now, this cult favorite stays one-of-a-kind.

Anaconda
Anaconda starred Jennifer Lopez, Ice Cube, and Owen Wilson. When it first hit theaters, critics tore it apart. But over time, it found new life as a so-bad-it’s-good cult classic. The story follows a documentary crew on a wild hunt for a legendary giant snake.
The script is clunky and the characters are flat, but the lush setting and campy tone make it weirdly fun. Jon Voight’s unhinged performance adds to the charm. A new meta comedy remake is now in the works, poking fun at the original.

Colossal
Colossal has such a strange and wild premise. The film tackles heavy themes like alcoholism and toxic relationships, all through the lens of rampaging kaiju. Anne Hathaway delivers one of her best performances as an alcoholic who unknowingly summons a giant monster in South Korea.
The idea of using giant creatures to represent personal flaws was unique. However, it made the movie tough to market. Despite strong reviews, the film didn’t find its audience. Missing Colossal is truly a colossal mistake.

Grabbers
Grabbers doesn’t reinvent the horror-comedy genre. It delivers a wildly entertaining story you don’t often see in monster movies. The film is set in a small Irish town that gets invaded by bloodthirsty creatures. Their only weakness is alcohol.
To protect themselves, the locals stay drunk as long as they can. The results are both ridiculous and genuinely funny. The creatures look convincing thanks to impressive special effects. Unfortunately, Grabbers didn’t get the acclaim that other horror comedies earned.

The Monster Squad
Director Fred Dekker didn’t stop at one cheesy ’80s horror flick. He followed up with The Monster Squad. It dared to ask a simple question: What if The Goonies fought the Universal Monsters? The result is a wildly entertaining ride.
They also face the Wolfman, Frankenstein’s monster, the Mummy, and even the Gill Man. Despite Stan Winston’s groundbreaking creature designs and a witty script, the film flopped. Today, it proudly wears its cult-classic crown.

Split Second
Split Second unfolds in a flooded London. Its promising story and themes should have made it a bigger hit. A murderous creature emerges from an environmental crisis. Rutger Hauer stars as the detective hunting this relentless monster.
The film takes itself too seriously. This makes it hard for viewers to stay invested. Years later, fans now celebrate its unintended humor. If it had leaned into comedy. Its environmental message and monster threat could have echoed classics like The Blob or The Stuff.

Slither
Back before James Gunn was tapped to reboot the DC Universe. He earned his stripes as the writer of the live-action Scooby-Doo movies. He also penned Zack Snyder’s Dawn of the Dead remake. Gunn made his directorial debut with Slither.
It’s a B-movie throwback to the gooey ’80s sci-fi horror of The Blob. Alien slugs crash in a small town. They infect residents in a hilarious and gruesome thrill ride. Nathan Fillion leads with Elizabeth Banks. Michael Rooker makes it unforgettable.

Splice
Splice premiered to positive reviews but underwhelmed at the box office. Adrien Brody and Sarah Polley play scientists who splice human DNA with animal DNA to create a creature called Dren. Dren’s threat escalates.
The standout performances and emotional depth set it apart from typical monster movies. Some of the scenes are disturbing. Overall. The premise satisfies but offers little new formed sci-fi and horror fans.

Jennifer’s Body
Jennifer’s Body was Diablo Cody’s follow-up to Juno but did not match its box office success. This underrated Megan Fox horror flick’s emo-style scares and dark humor have earned it cult status. It follows a teen girl who becomes a succubus and hunts her high school’s male students.
Poor marketing pitched it as a sexy thriller for teenage boys. Fans discovered it late. Its flop hurt Cody’s and Karyn Kusama’s careers. It killed any chance of a sequel.

Love And Monsters
Love and Monsters skips horror tropes. It tells a coming-of-age story in a world overrun by monsters. The movie was set to open in March 2020. It played in a few theaters. That delay kept it from finding its audience sooner. Critics and viewers praise the movie.
It stars Ariana Greenblatt, Jessica Henwick, and Dylan O’Brien. Dylan’s character, Joel, journeys across the apocalypse to reunite with his girlfriend. He gains confidence, learns the value of community, and finds humor in the chaos.
Discover the these monster movies may have flopped, but they’re secretly brilliant and deserve a second chance!
