Film is a perfect medium for delivering a political punch to your face, after which you can wash off the gloss that was deemed necessary for the film to be seen my millions, evaluate the facts you were offered in the light of new or existing ones, and make up your own mind. That's the whole point of good, biased political documentary, as summed up by Michael Moore at the very end of this one. There are enough millions of people who are completely oblivious to critical issues that a well prepared, biased, flawed, powerful punch can wake them up to, who do not otherwise stand a chance of forming a stance for or against and getting involved in those issues. Delivering punches and sitting down calmly and evaluating sophisticated issues thoroughly in an impartial manner should not be mutually exclusive; there's room for both.
