Sean Parker's character is undoubtably the catalyst for the rift that occurs between Mark and Eduardo. Timberlake pulls of the character excellently as the manipulating businessman who uses his rockstar swagger to convince the socially inept Zuckerberg that in order to suceed he must be ruthless and that if his best friend gets left behind, "we get left behind." Network is a smart film, so smart in the fact that the audience is often overwhelmed with the sheer amount of information beng thrown at them, however this sense of confusion only serves to help the audience understand the kind of manic energy involved as a bunch of twenty somethings create one of the highest grossing online industries ever concieved. The Social Network succeeds in portraying both the drama of facebook's creation and the reason behind why 500 million of us have signed up in the first place. While it's not important to the plot anyone with a facebook page will undoubtably be interested to know how pieces of it first fitted together.
The minute details of the plot are questionable, the specifics of Zuckerberg's relationship with his ex girlfriend have been debated but whether or not the plot is 100% accurate is besides the point when viewing a film like this. Fincher takes a story of corporate disputes and courtroom battles and injects it with such life and energy that it is easily as entertaining as any of the year's so called blockbusters. At the end of the second act things begin to slow down however the humour and style of the piece keeps holding the viewers attention until things pick up towards the conclusion. However it's in the quiet moments where Fincher really flexes his directorial muscles. More powerful than any of the intense dialogue sequences is in the final moments of the film as Mark sits alone at his computer hopelessly refreshing his facebook page awaiting his ex girlfriend to accept his friend request, desperatley hoping for comfirmation that he's not as alone as he knows he is. The Social Network is a classic tale of betreyal, revenge and alienation for the Silicon Valley age and is not to be missed.
