I recommend watching Inside Job : http://www.sonyclassics.com/insidejob/

it's a nice documentary about the 2008 financial crisis.

Good side: it explains well how the crisis was unavoidable and why the financial market is defective by design.

Bad side: a good part of the movie is more sensationalism, taking a lot of time to underline that people in the financial sector spend their money in drug, whores and expensive yachts. (how they spend their money is, IMHO, completely irrelevant, the interesting question is how they earn that money)
