Inside Job
A good and clean explanation of how US side of the 2008's global economic crisis was nurtured. Really well cut and simply explained so everybody can understand it. Also, a good introduction to all the main characters with certain degree of responsibility in the US. A pity that the POV from the very beginning is that the system was perverted and doesn't go forward. You would miss a critical analysis on whether the capitalist system works at all or systematically causes these problems because it is in its own nature.
