Sasha Grey's Performance
I think she did okay, she wasn't incredibly brilliant, but not god-awful. There were parts where I thought her acting was painfully flat, like when she was fighting with her boyfriend about the trip. On the other hand, though, there were parts when she definately came alive, like when she was telling the customer about the man with the q-tip, she seemed genuinely upset and disgusted.
I think maybe with a handful of acting classes and more experience, Sasha Grey could be a successful mainstream actress, she's certainly beautiful enough.
