You'd have to be slightly nerdish to like it.

Yup, I'm one of those people that liked it but wasn't flabbergasted like most other people. I still don't get why I'm pulling the short straw, statistic-wise, though.
Let's face it ; movies are not documentaries unless the story behind them is really - and I DO mean REALLY - good. This is just a story following money and nerds.
Sure, there's emotion there (you'll have to sit through a large chunk of the movie before being able to detect it) and sure ... there's a good story there but are you really interested in it or is this one of those (less and less frequent) success-story-searching "I wish I was him" stories? It's probably me but I loathe the psychology behind this scheme.
Look folks ... read financial history and check how many heroes an antagonists could have been created on this movie's meager standards.
If you're really interested in the story behind FaceBook then this movie is a must. If you like good movies though .. then this is one you'll be happy to have left alone for a few years. Wikipedia is, in my humble opinion, a more interesting source in this case.
