This is a movie I had such mixed feelings about that it changed me - I have to give it 5 stars.
The story is a fictionalized version of the creator of Facebook. I was intriqued, appalled and finally impressed by this very complicated human story. Facebook was created by Mark Zuckerberg, an antisocial undergrad computer geek, a social climber who loses his girlfriend and creates this site to prove himself.
Facebook's amazing success leads to lawsuits, charges of theft and losing his only friend. His isolation is very real and touching, yet you're pushed to disliking the cocky nerd. I loved it for the very human dilemma of isolation through net relationships and how suffering follows any success story. It transformed my indifferent use of Facebook because I quit it the very next day. lol!
