David Fincher’s The Social Network (B) tells the true-life story of the founding of Facebook. Its fairly unlikable hero Mark Zuckerberg (Jesse Eisenberg) aside, the film is a glossy and smartly told story about the lengths folks will go to protect their vision and invention and how stone-cold they can be in discarding friends in the process. Andrew Garfield gets a “like” for his performance. Armie Hammer is also good in two performances as twin investors jilted by Zuckerberg. The film is a bit austere, cold and calculating like its subject, which doesn’t take away from its craftsmanship but maybe from its endearment.
