Memento is an awesome movie. I have seen it multiple times, and it has continued to be an amazing movie. The whole entire plot seems to keep you guessing, which is the point of the movie. One always wishes to know what actually has happened or is going to happen to this man with this "disorder", as he says. There are some great characters in the movie, though most are just selfish and cruel individuals. Memento is labeled as one of the "mind-fuck" movies, and it goes extremely well with this label.
These types of movies are some of my favorites. They are always great and always keeps me on my toes through out the movie. I always enjoy movies with some type of amazing twist at the end of it, because these "twists" usually allow me to think more about myself and life, in general.
Anyone have any good suggestions of less popular end-twist movies?
