I watched Black Swan finally, but it was really disappointing IMO. Little things that annoyed me included the fact that it took too long to get moving and the fact that Natalie Portman was sickly skinny (grossed me out).
A bigger annoyance was that the film hit a bit to close to heart. I've been swimming on a club team for 10 year (now up to 15 hours a week 50 weeks a year) and I've seen the pushy parent and overpowering coach thing way too many times. It's not uncommon for people to have complete breakdowns under the pressure. I've distanced myself from a lot of my swim 'friends' because the competitive shit and pressure from everyone really just makes you want to bail out. Creepy shit watching it happen in a movie, knowing that could easily be someone I know.
