I thought it was a very well made movie, and Fincher has a way with these kind of scripts that lack a traditional story arc that leaves them compelling anyway.

It is kinda funny that Sean Fanning's name in the movie is Sean Parker. Or was that character supposed to be someone else and to protect the identity they claimed he made "napster" instead of whatever he really made? Certainly Timberlake looks nothing like Fanning.

I think the movie is a bit kind to Zuckerberg, but then, it is pretty hard to make a movie focused on a single individual and not have it come out sympathetic. Unless that individual is, say, hitler or idi amin.
