Yeah, I also thought Hammer was great in this, as well as everyone else, including Timberlake. I think The Social Network is the closest thing to a flawless movie we had in 2010. Even that ending is spot on for what Sorkin decided to do - the movie (not Zuckerberg's life) is all about a dude who can't really communicate with people very well and wants that girl back. The ending was the good kind of painful. I loved it.
