15 Most Unwatchable Movies of All Time, Ranked

It is an inevitability, no matter what the medium or concept, that for every groundbreaking and exceptionally high-quality piece of art or creation, there will also be examples that fail to meet the mark and disappoint. This exact concept also applies to movies and filmmaking, as every film can't be a stunning masterwork made with the highest quality in mind, as there will always be those that fall below the standards of quality. However, some films manage to go above and beyond in terms of their complete lack of any redeeming qualities, rendering them nearly unwatchable as a result.

It takes an especially painful and egregious execution to create an unwatchable film, being distinctly different from a film simply being terrible in every way. Even many of the perceived worst films of all time, like Manos: The Hands of Fate and The Room, have so-bad-its-good qualities that make them highly entertaining watches for all the wrong reasons. To become truly unwatchable, a film has to find a way to completely lack entertaining qualities in the worst way possible, whether it be through shocking and uncomfortable content or just overall dull pacing.

15 'The Last Airbender' (2010)

Often considered to be one of the worst movie adaptations of all time, it's difficult to get through even a single scene of The Last Airbender without it spitting in the face of everything that the original animated series stood for. Even outside its systematic betrayal of the source material, this wannabe blockbuster is an absolute slog to sit through, having nothing in terms of character or charm and being a complete bore from beginning to end.

The film has absolutely nothing to offer in terms of action, storytelling, or even visual effects, with everything that it attempts to do being outdone by both the original animated series and even the recent live-action series. Time has only made The Last Airbender's complete disregard and betrayal of an adaptation that much more irredeemable, making it a blemish on the outstanding legacy of one of the defining fantasy stories of the 2000s.

14 'The Human Centipede 2 (Full Sequence)' (2011)

While the original Human Centipede had already achieved an infamous nature for its depraved and sickening premise, it, for the most part, felt subdued in its execution and was more about the insanity of the doctor at the center than the actual grotesque nature of his experience. However, this same restraint cannot be said about The Human Centipede 2 (Full Sequence), which goes out of its way to gross out and disturb the audience with the most over-the-top gore and depravity.

It quickly reaches a point where it isn't even fun to sit through its onslaught of gore, as an existence entirely defined by shocking the audience is an existence not worth the time or effort. There's an argument to be made about the film's deeper messaging about the perception of art and how messaging can be muddled by an audience, yet that doesn't stop The Human Centipede 2 from being near unwatchable in its execution.

13 'Music' (2021)

While Music was created with wholesome intentions of bringing attention and a voice to people on the autism spectrum, its execution proved to be so ineffective that it felt more like a problematic caricature than a genuine step forward. It becomes clear that wanting to be a feel-good rallying cry for the autism community is only a secondary goal for the film, whose main goal is to boost the social capital of director/popstar Sia and a jumping-off point for a bunch of her music.

As if being actively insulting with its depiction of autism wasn't bad enough, some of the messages that the film presents are not only incorrect but actively harmful to teaching people about those with autism in their lives. It's frankly unforgivable just how much the film uses autism as a prop for its own agenda, as it has been rightfully forgotten in the short time since its release.

12 'The Legend of the Titanic' (1999)

Being at one point the highest-grossing movie of all time and a worldwide phenomenon that defined '90s filmmaking, it was inevitable that other films would attempt to copy and ride the coattails of James Cameron's Titanic. One of the worst of these Titanic rip-offs is the Italian animated film The Legend of the Titanic, which mostly copies the plot of Cameron's film with the implementation of talking animal side plots and a complete disrespect for the original tragedy itself.

While it's already bad enough to water down and diminish the emotional impact and effectiveness of its romance story with an array of annoying talking animals, the biggest issue of The Legend of the Titanic comes from its rewriting of the historical event. In an attempt to make the film more family-friendly and safe for all audiences, the film features a giant octopus who ends up coming to the rescue after the crash, saving all of those aboard the Titanic. Through its rewriting of history and actively spitting in the face of the legacy of those who lost their lives, it's hard not to feel sick and disgusted with The Legend of the Titanic.

11 'Leonard Part 6' (1987)

One of the biggest culprits for truly unwatchable films is a failed comedy film, as while the failure of any other genre results in unintentional comedy, failure in the realm of comedy only results in awkwardness and boredom. As far as '80s comedies are concerned, few are as uninteresting and painfully dull as Leonard Part 6, the Bill Cosby-led spy parody without a single good joke. Even without the poorly aged modern context of the heinous actions that Cosby has committed, this film still wouldn't be worth watching due to its complete lack of care or effective gags.

Leonard Part 6 is one of the quintessential examples of how poorly a comedy film can end up being when it completely drops the ball in the realm of comedy, with the resulting film being a painful slog whose short 85-minute runtime feels as if it's going on forever. Considering just how prevalent and prolific spoof and parody movies were in the '80s, it would seem as though this film would be a surefire hit, yet it does nothing interesting with its concept and pales in comparison to actual great spoof films of the era like The Naked Gun.

10 'Slender Man' (2018)

A once major figure in the world of internet horror, it certainly makes sense that a feature film revolving around Slender Man would be released, yet this painful and uneventful snoozefest ends up doing a major disservice to the legacy of the character. The terrible and unwatchable horror movie was directly impacted and plagued by real-life tragedies that forced filmmakers to tone down the more mature themes and scares to get a PG-13 rating. It's difficult to imagine the film working even if it maintained its original vision, but the final result has genuinely nothing to offer in terms of a supernatural horror film.

For a film titled Slender Man, it features very little of the monster himself, with the majority of his scenes and scares being cut during the film, and instead focuses on a group of wholly unlikable and generic teenage girls. When he finally does decide to provide some scares for the audience, it ends up being largely watered down and ineffective due to its overabundance of cheap jump scares and uninteresting visuals. There's certainly a correct way to tell this story and do the character justice, yet Slender Man manages to be the absolute worst way to make a movie about the character.

9 'Bolero' (1984)

One of the most disgusting and uncomfortable romance films of the 80s, Bolero has lived in infamy ever since its release through its combination of boring execution and sickening implications. While stories of young women getting in touch with their sexuality and romantic side have found success both before and after the film's release, Bolero's shocking and uncaring execution of its story makes it morally abhorrent to watch unfold. It finds the worst possible balance between being wholly uninteresting and boring in one second and having shocking, distasteful underage nudity in the next second.

The film has achieved notable status as the only film to feature both a 0% on Rotten Tomatoes and an F from CinemaScore, cementing it as a film that nobody has found any enjoyment in. There is nothing romantic or tantalizing about the story and sequence of Bolero, managing to instead create an essence of pure disgust and anger through its shocking content. The film has all the writing strength and filmmaking execution of a poorly made porn sketch with the gravitas and self-entitlement of treating it like an auteuristic work of art.

8 'Kirk Cameron's Saving Christmas' (2014)

Faith-based filmmaking is often a relatively easy punching bag when it comes to ineffective filmmaking whose focus is in all the wrong places, yet films like Kirk Cameron's Saving Christmas prove to make all of these criticisms and complaints ring true. The film only barely meets the qualifications for being considered a movie, as it mostly comes across as a feature-length presentation from Kirk Cameron explaining why Christmas still rings true to Christian standards in the modern world.

For what is presented and set up as a wild fantasy comedy holiday film in the same vein as National Lampoon's Christmas Vacation or Home Alone, Saving Christmas offers nothing in terms of hijinks or holiday entertainment. While the film may hold some minuscule value for those looking for the film equivalent of a faith-based lecture, the vast majority of audiences and critics found this approach rather monotonous and boring, cementing it as one of the worst Christmas movies of all time.

7 'Disaster Movie' (2008)

One of the most widely despised and hated trends in comedy that thrived and dominated throughout the 2000s was the sleazy, raunchy take on spoof movies, focusing more on shock humor and references over actual good comedy. While any number of these films can be considered unwatchable in their own right, the worst of the worst has to go to Disaster Movie, a laughably bad attempt at satirizing the trends of large-budget disaster films.

The movie has the sense of humor and style of an obnoxious middle schooler who just learned how to swear, putting as many shocking and poor-taste jokes in the film with no care or restraint. While this at the very least sounds somewhat appealing to those who enjoy a darker sense of humor, the film quickly grows tiring and repetitious to the point of anger, further amplified by its uncaring approach to reference humor. This film's widespread failure would help bring an end to this trend of terrible spoof movies, as they are not nearly as prevalent as they once were in the decades prior.

6 '365 Days' (2020)

Taking the limits of erotic filmmaking to their absolute extremes, 365 Days goes out of its way to feature some of the most sexual content imaginable, taking focus away from any depth to its characters and entirely focusing on its eroticism. While a film being in touch with more sexual content isn't inherently a bad thing, 365 Days reaches a point of absurdity, almost feeling like full-on adult content in its execution, made worse by its deeply disgusting and problematic setup and premise.

The terribly written romance movie truly has nothing close to substance or meaning behind its erotic sequences, which portray a sickening power fantasy of a rich man kidnapping a woman and forcing her to fall in love with him. Even compared to other notoriously bad films that largely rely on sexual content, like Fifty Shades of Grey, 365 Days truly has nothing to offer outside its controversial sex scenes, with rarely even an attempt from the film to pretend otherwise.
