And for the record; anyone that thinks Eissenberg's character, Mark Zuckerberg was an asshole that ripped his friends off, let me shed light.
Think of it like this -- Zuckerberg is and artist, at what he does. The Winklevoss twins asked him to draw a woman, and the kid painted the Mona Lisa.
And the people he was allowing to run the business end of things (so he could concentrate on his "art") were the ones that squeezed his best friend Andrew out of the CEO role. But I think it's far more complex than petty jealousy. The lawyers probably suggested to Zuckerberg that his friend would be better off with .03% of billions rather than 34% of a million. So in a round about way Mark was looking after his friend, at the end of the day. Does that make any sense?
