I know I’m (very, very) late but I finally watched Black Swan and loved it.

Natalie Portman once again surpasses my expectations.
Brilliant atmosphere and interesting storyline.
Professional ballerinas are fascinating by themselves. Add to that the magnificent Tchaikovsky music, a beautiful cast of girls and a nice story about lack of mental health and this is what you get. A very entertaining and somewhat sad one hour and forty five minutes.

87% on Rotten Tomatoes and worth it.
