I hate to say it but I really feel for Mark Zuckerburg. I guess it was the opening scene after getting dumped by Erica Albright when he starts drinking and blogging on Livejournal. Who knew that is how to become a Billionaire is to: (Have ZERO ZLICH NADA Social Skills or Game with the Ladies) Thus fueling your sexual frustration and then not only flaming her, but taking it to an exponential level!
But yea, you have to give him credit for rising above the pecking order of society and becoming CEO, Bitch!
There were also some great references in this movie. One to Niagara Falls and the other one to the Original Karate Kid, which was too funny given the prototype of the members of Harvard Crew.
Did I also mention that the sound track is totally kick ass?

How can you go wrong with Trent Reznor. Some great pick for songs included California Uber Alles by the Dead Kennedy's. Also whatever electro/trance song that they were playing in the club when Mark is having an Epiphany with Sean Parker Mr Napster is just plain SICK!
Plus it was also a fun time seeing it with great company, someone who could also relate to references "back in the day" (e:theecarey)
In the end just go and see it. It's dark, yes but at the same time brilliant.
Glad it was a good time. Just wanted to add that there are two other movies about facebook but one of them is on the internet and I think is real. One of the phone companies has some promotion with facebook and someone on there has videos where they go meet people that they don't know but know through facebook. then there is another movie that is a horror/suspense movie where some guy falls in love with someone on facebook and goes to the house, from the previews it looks like an empty house. Now that I know this movie was good I may have to go see it....
Is this the film about the facebook inventor. I saw the trailer when I went to see Inception. Looked interesting
NB: I don't feel impelled to join facebook, regardless.
