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?
Peacock has a growing catalog that's worth exploring, especially if you've already burned through Netflix and HBO Max. Their sci-fi selection has some unexpected gems.
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.
