Fahrenheit...

Every review I've read about Michael Moore's "Fahrenheit 9/11" has been a good review. Most rave about the excellent filmmaking. But every single movie critic has not failed to mention that there is a lot of manipulation, propaganda, and "cut and paste" storytelling going on. I can understand having integrity, recognizing certain rhetorical fallacies and manipulative techniques in, say, a movie about dragons or dinosaurs or even love, but shouldn't a documentary be held to a higher standard? Shouldn't propoganda and manipulation be the sign of a bad documentary?

Am I crazy here, or is what the reviewers really saying is that the movie isn't a fair and balanced look at truth, but rather it's something that we agree with so we're going to give it a good review?
