The Corporation is complete crap! I was looking forward to a thoughtful analysis of the legal and social framework of modern corporations, but all it had was a bunch of hype. I think the director wanted to make a music video, but was stuck making a "documentary". It's just a bunch of metaphors and disjointed facts.
I've heard that Enron: The Smartest Guys in the Room is a much better movie. I'll check that one out.
