The Movie "Black Swan"?

Has anyone watched this movie? and does anyone know what the hell this movie is about? Me and my friend were bored one night and decided to "redbox" it. We decided on Black Swan cause it had supposedly won like all these awards. MAN we never been so disappointed! I truly wanted my $1 back LOL....I thought it was horrible....I didn't get it!!! Everybody kept saying watch it a second time and I would understand....NEVER....that's not going to happen again. Does anyone understand this movie and would they care to explain it to me. PLEASE!!!!!
