About
Choose it if you enjoy slow-burn psychological tension in a confined setting and don’t need constant plot turns; Not for you if you want a fast, action-driven thriller like The Hitch-Hiker or Purple Noon.
Pros: tense psychological drama; memorable lake setting; strong jazz score | Cons: slow, little “happens”; divisive atmosphere; some credibility/acting complaints
