I avoided this at the box office first-run. I just watched it (9/2012) on HBO. It is is very well made. The main reason I am writing this review is not only to let people know that it's interesting and moves along well. It's nothing like I thought it would be. More importantly, I have seen the film characterized in a number of ways in other reviews or summaries. There seems to be a consistent pattern of declarative statements being made about characters in the film in areas where the movie is ambiguous. One of the reasons I LIKE the film is because you can't be sure where reality ends and Nina's drug/pressure-induced imaginings begin. Mila Kunis's character of Lily is key in this area of uncertainty I am describing, but certainly not the only one. The thematic touchstone of people encouraging Nina to "Lose(her)self" sets the stage for this psychotic metamorphosis.
