It is a pretty good documentary on the Enron scandal, but somewhat lacking in detail in comparison to the book. They did a great job explaining how toxic Enron's culture was but the book did a better job explaining the player's backgrounds as well as the fraud itself.
I also wish they had gone into more detail on Lay, Skilling, and Fastow's backgrounds. I don't think it is an accident that a pipeline company run by an academic, strategy consultant, and structured finance guy ended the way that it did (destroyed their physical business to sell vaporware and financial engineering). Some of the pipelines they sold off for pennies to fund things like broadband trading are now worth billions (see Kinder Morgan)
If you really want to learn about all the financial aspects, as well as more on the character's backgrounds I suggest reading the book this documentary is based on.
