Mind twisting movies

I've become obsessed with watching movies with deeper and much more complex story to it. I like a movie that sticks in your head for a while. At first it might seem confusing but when you figure it all out, it gives you some kind of pleasure. Cause not each and everyone want to enjoy a movie by analyzing it. But I like to think of myself as one of them. Since I am a thinker, more than anything else.
