Bad Sci Fi movies are sadly common in the genre, as science fiction is a difficult type of story to tell on-screen. This is partly because it is expensive to realistically produce, but also because good stories seem to get lost in all the production design, the special effects and the costumes. This list reflects a number of truly bad science fiction movies, making them oddly amazing for actually being so bad and then released to the world to put them on lists on the internet. 

  1. "Robocop 3." Here's an idea for a bad movie: make a third version of a film that barely worked initially, and only worked because it had extreme amounts of violence, campy dialogue and a semi-cool main character as it's premise. Then remove most of the extreme violence, give it a PG-13 rating and make the dialogue even stupider. Definitely a funny film, but only if you have absolutely nothing to do with a Tuesday.

  2. "Bicentennial Man." Robin Williams does "the robot" over the course of a number of generations in a film that is beyond cheesy and really pointless by the time it is over. You'll feel like you have been watching it for 200 years by the time it is over, assuming you make it the full way through.

  3. "Species II." Natasha Henstridge starred in the original "Species" which is arguably as bad as the second one. However, while there was absolutely no story in the first installment of this bad sci fi stinkbomb, there was at least higher production values and a ton of fun sex scenes. In "Species II" however, you just feel like you're watching Cinemax after hours. And that's not a bad thing, but probably not the sci fi movie you planned on watching with your parents...

  4. "Mission to Mars." With a cast of Tim Robbins, Gary Sinise and Don Cheadle going to Mars, how could you go wrong? Two and a half words: Brian De Palma. Well, that and a script that makes no sense and a film that gets progressively cheaper, stupider and less sensical as it goes on. By the end you'll be wondering how any sane person could have actually spent money to make this movie, but that's a reoccurring question when it comes to any Hollywood disaster.

  5. "Battlefield Earth." What happens when a well-funded cult wants to make a movie? You get "Battlefield Earth," the L. Ron HuBbard Scientology train wreck that has been universally called one of the worst movies, not just bad sci fi movies, of all time. John Travolta stars and also funded much of the film, which also may say a lot about his connection to reality.
