Documentary films take you deep into people's lives. They were the first form of reality tv. Sometimes they can be hard to find since they don't get big advertising budgets and lots of press coverage.
Freedocumentaries.org is a library of documentaries that you can stream for free. There are a bunch of crazy anarchist-type pictures. But there are a few good ones in the mix.
Shut Up and Sing - Great documentary. I don't even like the Dixie Chicks and I loved it.
Control Room - The al Jazeera network and the Iraq War.
Fog of War - Robert McNamara discusses thoughts about Vietnam and his life. This movie will get you loving documentaries.
Why We Fight - Get ready to have your mind rocked as to how the military machine works.
