I’ve seen Maxed Out. It’s good but it is more about the credit card industry than the psychology of people who spend way beyond their means and those who pick at their financial carcasses. Personally I found it somewhat dull, I was much more interested in the human element than the mechanics of the credit and debt industries.
Enron: the Smartest Guys in the Room is amazing, however, and I highly recommend it. The little window into Jeff Skilling’s persona is chilling.
