Nothing new for most lefties The Corporation is quite a skillfully made documentary, but if you've any of read the books of the main authorities interviewed for the film - Naomi Klein, Noam chomsky and Michael moore, then a lot of the depressing subject matter of this documentary will already be pretty familiar to you.
For example, most people already know that corporations are destroying the environment, exploiting third world workers and controlling too much of our culture, for example.
Even though 'The Corporation' is rather long, i felt it ended up spreading itself too thinly - not surprising since the subject is so vast and complex. I think it might have been better to concentrate on more constructive aspects, such as what legal avenues could be available to us to reduce corporate power.
The film is a good primer and wake up call for people who are still oblivious to the out-of-control nature of corporate power, but doesn't add anything novel to what's already out there.
