The film tries to put a human face onto the banking meltdown of the last 2 years. It demonstrates the effect it had on people and the sort of person who might have got us there. This might be a laudable aim, but it's also slightly daft (as is the idea that we've "introduced socialism into the banking system," which makes me wonder why they've got a bug up their bum about socialising medicine.
The film is also a complete mess. Firstly, the efforts to personalise the banking crisis don't make sense. It can't be put down to a person or two, or even a type of person. We were all responsible, and by shifting the blame onto the banker, it feels like he's lessening our role in it. Secondly, there are times when Stone (the director) feels the need to speechify and explain stuff to us. This could have been judiciously pruned, to make it flow better. At the moment it doesn't, and at the most people were left thinking how muddled it was because of that.
