Where to start with this movie. First things first, the acting and pacing of it is immaculate. It keeps you in and at the edge of your seat without feeling rushed or bogged down. The line between insanity and reality are tied in a beautiful and impressive way that keeps you guessing all the way to the end. It's the kind of movie you can't watch just once and really you will want to see it again and again just to see and experience it. If any flaw can be found, I would have loved more of it. But that's my own preference for longer movies and nothing really against the movie's own quality. I can't recommend it enough.
