INSIDE JOB is an excellent explanation of what went wrong with the financial system and why there is a worldwide financial crisis. It does a good job explaining the history leading up to it and points out that not only were there warning signs, there were plenty of experts telling us about the warning signs. The film is very professionally made, perhaps a little too smooth for its own good. It would have been enough just to explain what happened, but in the last 20 minutes there's a little too much time on the soapbox repeating the flaws, extrapolating them to unrelated issues and trying to stir the pot for more reform. I certainly agree that reform and regulation is necessary, but I don't need a shot of the statue of liberty telling me that.
But I still highly recommend the film.
