I finally got around to seeing this one after having put off watching it for some time. I was skeptical of the hype surrounding it when it opened theatrically (hard to believe that was four years ago already), but I was pleasantly surprised to find it was an intelligently-written character drama about the personalities and dynamics involved in the creation of Facebook, and what happens when that website quickly becomes a bigger cultural phenomenon than anyone could have expected.
Jesse Eisenberg carries the film well with a quiet yet intense performance as the brilliant programmer whose social networking website connects millions of people online, yet struggles with the human connections around him, poignantly conveyed in the final scene when he sends his ex-girlfriend a friend request and anxiously re-loads the page to see if she's accepted it.
Aaron Sorkin's economic and tight script wisely focuses on the larger implications of the story and avoids getting hung up on the minor details of Facebook's creation. David Fincher's direction is subtly effective, building real suspense out of the situations and tensions between the characters without becoming melodramatic.
