I think the title sums up my question. Psychological thrillers/twisters are my favorite kinds of movies, and I feel like I've run out things to watch. Anything that really will make you think, has a great twist, is disturbing, etc. I'll list a few below to give you an idea of what I mean, but please list more suggestions if you can.
The Sixth Sense
American Psycho
Fight Club
Memento
The Machinist
The Shining
Eyes Wide Shut
A Clockwork Orange
Se7en
Requiem For a Dream
The Silence of the Lambs
That's a small sample of what I'm referring to, I think you get the idea. Please list other great suggestions and if possible try not to repeat ones that have already been listed. Thanks!
