Help! Documentary suggestions??

Help! I need to write a paper on a documentary for my class, but I'm not really big on watching documentaries... The only requirements are they it be of something appropriate and about peoples lives.. anyone have any suggestions for a good one to watch. I don't want to have to watch anything boring..

Night and Fog.

Guns, Germs & Steel

It's a two disc doc, but it's entertaining. This is the doc I recommend first, when people ask me about watching a good doc.

Jaden's recommendation is also a great one. 'Night of the Long Knives' is another decent Nazi doc, if you're into that.

Paradise Lost- The child murders at Robin Hood Hill. http://en.wikipedia.org/wiki/index.html?curid=183907

There's actually a follow up documentary to the case. It's just as, if not more compelling than the first. you should really try to check it out. It would be hard to write a paper on it, but if you could, you'd get aces across the board.

I saw "The Black List vol. 2" recently and it was very good Trailer: http://www.youtube.com/watch?v=7-teE13p-kE
