Sci-Fi is where filmmaking ambition meets audience imagination. Critics get distracted by whether the science is 'hard' enough or the metaphors are deep enough. Audiences care about one thing: did the movie blow their mind?
MGM+ streams much of the MGM and United Artists library. These are its sci-fi movies that audiences rated highest.
From space epics to cyberpunk thrillers to mind-bending time travel, these are the sci-fi films that real viewers rated highest.
Every movie on this list is ranked by ThumbScore — the percentage of everyday people who liked the film. No critic gatekeeping, no algorithmic manipulation. Just real audience verdicts.
