Mark Zuckerberg is an evil asshole. Who cares? Strangely, I found his characterization in this film to be sympathetic. But, forget this film is nominally about Facebook. It's not interesting from that point of view. This is an Aaron Sorkin film all the way (dir. by David Fincher). If you like his work, you will enjoy the film. If you look at it from any other angle all of its shortcomings will smash you in the face.
Best film of 2010 so far for me.
On a fall night in 2003, Harvard undergrad and computer programming genius Mark Zuckerberg sits down at his computer and heatedly begins working on a new idea. In a fury of blogging and programming, what begins in his dorm room soon becomes a global social network and a revolution in communication. A mere six years and 500 million friends later, Mark Zuckerberg is the youngest billionaire in history... but for this entrepreneur, success leads to both personal and legal complications.
