"Stacker compiled IMDb and Metacritic data from September 2022 on all sci-fi movies with more than 2,500 votes on IMDb. It ranked them by Stacker score, an equally weighted index between Metascore and IMDb user rating, #1 being the worst. Ties were broken by IMDb votes, meaning a movie with more votes would be closer to #1 worst. If a film did not have a Metascore, it was not considered.
This list includes movies that didn't splurge for a special effects budget, told a story that's been told too many times before, or didn't make sense. Some of these films are so bad their directors denounced them, while others have garnered cult followings."
