Fincher and Sorkin pull off the impossible by making this potentially embarrassing docudrama about the creator of Facebook into a fictionalized account as significant, if less cinematically powerful, as All the President's Men. While Mark Zuckerberg never rises to the level of either a heroic or a tragic figure, Jesse Eisenberg (who I didn't think capable of embodying a character other than the role he was born to play in The Squid and the Whale) makes this sad techno genius into a deeply compelling character.
