I loved the social network. I absolutely adored it.
Looking back in hindsight I think it must have been because it made programming seem cool which I never thought was possible. Programming I thought was supposed to be a largely solitary activity with a geek hammering away at his keyboard but social network turned it into something else by showing the thought process behind it. It was cool the way Zuckerberg described the way he hacked into the all the systems as well. Do a wget. Just write a bash/perl script. Things, words I never thought would find their way into a film ever. The drinking sequence to choose the interns at facebook. The way Justin Timberlake played the flawed but incredibly charismatic Sean Parker(Remove the 'the', its cleaner).
The way the Winklevoss Twins lost the rowing race with Hall of the mountain king playing as the background score. Brilliant. Probably my favorite cinematic moment of the year.
Also they showed Zuckerberg using Linux on a sony vaio laoptop which was amazing. Think back to the big budget hollywood movies and all of them have their own interfaces to do cool stuff. Here Apache was the hero and you could actually see the the mods they had applied to the server.
The writing was just fabulous. What fantastic lines. Just probably the most quotable movie of the year, indeed in a long time. I will never ever forget the arithmetic scene. Fuck The Social Network was bloody awesome.
