Criticism: If this film doesn't make your blood boil, watch it over and over again until it does.
Enron functioned as the equivalent of an enemy nation-state (in economic, not geo-political terms) at war against its "clients," specifically the state of California.
This is old news, you say, and in the past, you say? The same selfish greed that fueled Enron is (and has been) fueling our current economic 'crisis'. This is what happens when you turn over control of valuable resources to obsessive-compulsive individuals who should be kept away from the general public.
An excellent case for the necessity of good governmental efforts to oversee the madness and insanity of the so-called "free market".
