Although Lay and Skilling are in some senses detestable characters (to my liberal morals) there is something compelling and charismatic about them and their rise to power and wealth. There is something of the Gordon Gekko about them.
It's a slick, fast-moving documentary of talking heads, reconstructions, and stylish montages of stock market tickers, high-rise office blocks, and trading floors. There are some astounding audio tapes of Enron's traders' conversations about manipulating the California power grid during the rolling blackouts. Their greed and ruthlessness is disgusting, but compelling.
Nugget: a hugely enjoyable and interesting documentary, impeccably executed and through-provoking, without being overly polemical or moralizing.
