I finally saw this the other night, and was horribly disapointed after all the hype. This was in no way a 'psycho-sexual thriller', mainly because there was never any doubt that this was all in her mind (and very little sex). It was pretty much the story of one person's breakdown.
I have to say, the mom came off way more sympathetic than I was lead to expect (the problem with reading reviews ahead of seeing the film, I guess). I was expecting a raging stage-door-mommy-dearest-monster-mom, and instead got a very nuanced and surprisingly sympathetic performance by Barbara Hershey, who turned out to be pretty much justified with her concerns (but that masturbation sequence was pretty funny, I wonder if it was supposed to be?)
And, pretty much, I hated NP in the lead role. I get that this was supposed to be about the disconnect between a naive child-woman who just wasn't savvy enough to see the implications of, oh, that her director might have his own sexual agenda that might or might not have included Nina, and a prima ballerina who, by age (27? 28?) should have known about the sex and politics inherrent in the power-struggles of the company she'd been a part of for years.
I think this actually would have worked much better with a younger actress, where we could really believe that she was as naive as NP was supposed to be. Because, in the end, I just found it not credible. NP didn't do a good enough job of making me believe she was as naive as she was supposed to be.
And yeah, I was expecting much more of the dancing, after the hype and this thread (kinda 'meh?', when all was said and done, -and I did pratice ballet for 8 years, and was only allowed en pointe after 7).
