Shutter Island
This movie seriously messed with my head in the best way. Leonardo DiCaprio was amazing in this. Scorsese blends the psychological thriller and noir vibes together so smoothly without it ever feeling too much. The whole movie has this super tense atmosphere, and the lighting, music, and camera work make everything feel really claustrophobic and unsettling. DiCaprio totally carries the emotional side of the story, and that ending changes the way you look at everything that came before it.
