It might do. It's very difficult to judge the film from a British perspective. The film doesn't give away much new information to someone reasonably aware of current affairs, but then it's not aimed at us. It is manipulative (but then again anyone who cries 'it's biased' is clearly an idiot; surely no one ever imagined it was agenda-free?), and there's a few sections where Moore editorializes unnecessarily - the scene of Bush in the school when the planes hit the WTC is what I'm thinking of. The scene says enough as it is, without necessitating Moore's voice over suppositions of what Bush is thinking. That said, I do broadly agree with Moore's appraisal of Bush, even if I frequently disagree with his methods, and the American population could well do with getting more interested in their own political system. Not that we're immune to disinterest here, of course.
