To acknowledge this side of the genre, 24/7 Wall St. has compiled a list of the worst science fiction movies of all time.

Detailed Findings & Methodology

Even as we celebrate such cinematic icons as “2001: A Space Odyssey” and the various Star Wars films, we also must turn our attention to the worst and campiest sci-fi films of all time. Movies such as “ Bride of the Monster,” directed by Ed D. Wood Jr. and starring Bela Lugosi, have generated a cult following because of their awfulness. In fact, bad sci-fi was behind the 90s’ cable television program, “Mystery Science Theater 3000,” whose premise — a captive in space forced to watch bad movies — was intended to chide the genre.

Because of the nature of the material and reliance on special effects and makeup, science fiction films are particularly vulnerable to failure. But sometimes, even the title can be a giveaway, like the 1964 film “Santa Claus Conquers the Martians,” “Attack of the Killer Tomatoes” in 1978, and “Hot Tub Time Machine” from 2015.

None of these movies gets the nod at the worst of the lot. That distinction goes to “Leonard Part 6.” The movie starred Bill Cosby as a retired CIA agent trying to thwart a vegetarian from seeking world domination.

To determine the worst science fiction movies of all time, 24/7 Wall St. created an index based on each film’s Rotten Tomatoes average critic rating, Rotten Tomatoes average audience rating, and Internet Movie Database average user rating. To be considered, each film had to have at least 10,000 Rotten Tomatoes and IMDb user ratings, 10 approved tomatometer critic reviews, and be classified as a sci-fi film by IMDb. Although many superhero films are considered to be sci-fi by IMDb, they were excluded as were other films that were deemed to be too far outside of the genre.

We averaged the user ratings from Rotten Tomatoes and IMDb and weighted by the number of votes for each. The combined user rating was then averaged with the Rotten Tomatoes critic rating.
