Abso-fucking-lutely amazing. Aronofsky quality and nothing less. Definitely one of my favorite movies, although I must say: all three of Aronofsky's movies rank high on my list of favorite movies.
Aronofsky admits this movie to being open to interpretation. My friend and I both think that the synopsis on the back of the DVD is very very bad... it forces an interpretation, and not the interpretation that the film left us with anyways.
