Its taken about 2 months of mulling over this movie to decide that its my #1 of 2011 and certainly one of the best I've seen in a few years. Its not even a character study as much as just a study of the idea of addiction. Its sex addiction, because drugs and alcohol seem too specific unto themselves. Also, there's a bit of a misconception that sex addiction isn't real. This amazing film shows, not so much the horror of addiction, but the pure misery of it. Because it is sex, which can and should be enjoyable, that is making someone miserable is very effective. The best part is the dynamic between him and his sister. Just her existence, and knowing that she has her own brand of screwed up-ness going on, tells us all we need to know about their childhoods. Simple and powerful. And generally amazing!!
