About
You’ll likely enjoy this if you want a moody, retro sci-fi horror that leans on suspense and unsettling ideas more than gore, in the vein of The Thing from Another World; Not for you if you dislike slow, dialogue-heavy investigations.
Pros: tense, gritty atmosphere; strong central performance; intriguing sci-fi mystery | Cons: slow early stretch; dated science details; talky police procedure
