Interesting and challenging, though I’m not sure that the ideas in the film were explored as well as they could have been. Despite her obnoxious pretensions of being the cinephile’s porn star in interviews, Sasha Grey’s performance gives exactly what is demanded of her and she does a fine job. The movie has segments where it feels like a beautifully photographed mumblecore movie, and that’s not a compliment. I feel I need to see it again before I can say whether or not it was good, but it was interesting, but not necessarily compelling or engaging on the first viewing.
