10 of the Worst Movies of All Time

Starring John Travolta, this infamous sci-fi mess is considered one of the worst films ever made.

Adapted from L. Ron Hubbard's novel, the entire movie is a confusing blur of poor acting, tilted camera angles, and a plot that feels like a desperate attempt to mimic a "Star Wars" movie without understanding what makes "Star Wars" work.

With scenes that make absolutely no sense and dialogue that could make an alien cringe, this Warner Bros. release stands out as a low point in sci-fi cinema.

M. Night Shyamalan took the beloved animated series and turned it into a live action disappointment. With mispronounced character names, a completely bizarre script, and uninspired performances, this film managed to disappoint both new audiences and long-time fans of the Fire Nation saga.

From its baffling handling of source material to its lack of chemistry among cast members, this was a fantasy movie with no magic.

This fourth entry in the franchise is notorious for its plot about a shark tracking a family from New England to the Bahamas—yes, really.

The movie features an older woman battling a shark in a sequence that feels like a parody of the entire franchise.

It's not just a bad sequel; it's a movie that makes the other sequels look like Best Picture contenders.

Pauly Shore and Stephen Baldwin star in this environmental comedy gone wrong. Trapped in a scientific dome, the two characters spend the movie annoying scientists and viewers alike.

With dumb jokes, obnoxious behavior, and a plot that goes nowhere, Bio-Dome feels like a summer camp skit stretched out for two hours.

Directed by Uwe Boll and starring Christian Slater and Tara Reid, this horror movie is based on a video game but feels like it’s based on a dare. Between its nonsensical story and laughable effects, it’s hard to believe this ever saw the inside of a theater.

This Uwe Boll film has often been cited as a low point in horror movie history—a genuine disaster movie, even without the natural catastrophes.

While fans of the video game might find moments of joy, this movie adaptation fell flat in nearly every way. Jean-Claude Van Damme plays the American hero, and Raul Julia’s last performance as M. Bison is the only watchable part.

The rest is an awkward mix of poor acting, bad jokes, and a baffling plot. It was supposed to be a great movie for fans but ended up being a cautionary tale for video game adaptations.

If you thought talking babies could be fun, think again. With toddlers speaking in full sentences and participating in spy-style antics, the CGI is creepy, and the script is worse.

It’s one movie that made audiences question how bad a kids' film could get. Even kids weren’t amused.

A cast stacked with names like Halle Berry, Hugh Jackman, and Richard Gere couldn’t save this sketch-comedy train wreck. With awkward sex scenes, offensive jokes, and scenes that fall flat, it feels like the whole movie was designed to test just how low comedy can go.

Rather than comedic effect, it generates cringe. Viewers often ask, was this even worth watching?

Sony’s attempt to build a cinematic universe around Spider-Man side characters gave us this confusing, unfunny mess. With poor dialogue, random plot jumps, and characters who seem confused to be there, it was the comic book movie nobody asked for.

Adam Sandler wasn’t in it, but the film might make you wish he were—at least it might have been intentionally funny.

A sequel so bizarre that it retcons the entire first movie, "Highlander II" turns immortal warriors into aliens and rewrites everything fans loved. Featuring Sean Connery and Christopher Lambert, this movie tries for epic but ends up as a confusing blend of sci-fi and fantasy that just doesn’t work.

Fans of the original Highlander call it the worst sequel of all time, and for good reason.
