Don't be put off by the less than subtle cover, or by the first few minutes of in-your-face agitprop - this is a thoughtful and well-constructed polemic against the power of big business. It seeks to persuade not by hysterical finger-pointing, but by exposition of facts and by interviews with well-informed individuals from the media, the corporate world and academe. Half of the interviewees are corporate "insiders", some of them glibly agreeing that there should be more regulation of business, some of them arguing, amusingly, that the problems of the world are due to residual excessive government regulation.
Above all, this film is highly informative. It starts with a history of the corporation, which, in case you didn't know (and I didn't) is a company with the legal status of an individual human being. This is interesting implications for accountability: when a corporation acts illegally, usually the worst than can happen is an expensive fine or out-of-court settlement. Prison sentences for individual directors are usually out of the question, because the entity acting illegally is the business, not the individuals who run it. It is also interesting to find out that a corporation has a legal DUTY, in the United States, to put the interests of its shareholders above all other considerations.
The film traces how lobbying has concentrated power in the hands of the corporations, to the extent that they are today at least as powerful as the politicians supposedly elected to represent the American people. Finally come some long case studies, including the (successful) attempts by FOX News to block the broadcast of a report by two of its journalists on the harmful effects of Monsanto's hormone treatment for cows to increase milk yield. It also describes the uprising that ensued in Bolivia after the World Bank insisted on privatisation of the water supply, so that even the unofficial collection of rainwater by its impoverished citizens was made illegal.
For those who like arguments made in bold strokes, the film's central thesis is that if the corporation is a legal individual, then its personality type is psychopathic. That rather facile metaphor might put you off, but don't let it, because the bulk of the documentary is restrained, informative, and thanks to the interview-based narration, comes straight from the mouths of experts. In the cases of those who support big business, they are often damned by their own words, either because they are so patently insincere and self-contradicting, or because they simply don't care what we think of them.
