I saw it and believe me, her nude scenes didn't help her "acting" ability. Best actress? By todays standards I guess anything goes.
Maybe you place too much significance on the nude scenes. I was commenting on the entire performance, in which she demonstrated that she is more than her looks - she has some range.
Perhaps I'm just generous or something, but the only problem I have with her is that she's crazy. I have no problem acknowledging her beauty and her talent.
