So I was persuaded to see this despite my instinctive reaction - ie, it's a movie about facebook, so how can it possibly be any good? - because of the Sorkin/Fincher connection, and indeed it sounds like it was written by Sorkin and looks like it was directed by Fincher. Anyway, it's a pretty good film - involving enough while it lasts, and with a story to tell - but not one that's likely to stay with me.
