To start off this movie is based on a true story. That is to say it's based on one side of a true story. Going even further it was based on a book based on an interview with the jilted co-founder of
What I liked: From the start you can tell it's going to be a fun watch if nothing else.
I didn't like knowing that there was a blatantly one sided story being told, and it was a smear campaign on Zuckerberg. This guy isn't likable as it is in real life what with his views on privacy, but shoehorning his life to fit the story was a bit cruel. It works as a movie and sometimes that's all that matters. In Butch Cassidy and the Sundance Kid the movie ended with a violent shootout, while in real life that never happened at all. Although at this point I think it's a bit insulting to the internet generation where information is at our fingertips constantly to put a story out there with the main crux of the story to be completely falsified. It belittles the story and the movie and the emotional resonance when (well I suppose if) you look up the real story after the movie. It's a good piece of fiction about an event that actually happened.
Why it didn't win the Oscar: The oscar voters are pretty old all things considered. Inspiring a nation to defeat the Nazis beats over the story of a little prick founding a successful internet company. Maybe it has something to do with another Oscar nominated movie as well: "I think positive emotion triumphs over negative emotion every time." -Inception. The King's Speech was inspiring, and that's kind of what a country in a depression needs at a time like this.
Anything else? I guess my final thoughts on the matter is don't rent this thinking that this is a true story, but don't be stopped from renting this because it's "the facebook movie."
