By far the best of the hits is "The Social Network" -- the most involving and complex look at the birth of an American business since "The Godfather Part II." It's an engrossing multiple-character study that's also a witty, lacerating, funny-sad depiction of runaway youthful creativity riding roughshod over any known concept of friendship and honor. Jesse Eisenberg is mesmerizing and elusive as Facebook founder Mark Zuckerberg, but even Justin Timberlake, with relatively few scenes, pulls off a multifaceted picture of Zuckerberg's sometime mentor, Sean Parker -- a cool, feckless, quasi-artistic new-media entrepreneur. (Above you see Eisenberg, left, and Timberlake, plotting their new-media empire.) And Andrew Garfield (future "Spider-Man") and Rooney Mara (future Lisbeth Salander) are revelations as, respectively, Zuckerberg's former best friend and ex-girlfriend.
