10 Greatest Sci-Fi Movies You’ve Probably Never Seen
A countdown-style roundup ranking ten low-budget, high-concept sci-fi films that trade blockbuster spectacle for philosophical density, from Moon and Primer to A Scanner Darkly at number one. The throughline is that these indie films (Primer especially) proved there was an audience for "hardcore" science fiction built on tight budgets, causal loops, and unsettling looks at human nature rather than special effects, with several entries explicitly tracing their lineage back to Carruth's and Vigalondo's low-fi time-travel puzzles. Worth keeping as a watchlist of overlooked, mind-bending genre films alongside the reasons each earned critical or cult recognition.
