If he is so sincere about telling us his message, why does he charge you $8-10 to hear it?

I don't recall Michael Moore having a problem with capitalism. He had staff, investors, and a distribution company to pay. He shouldn't need to martyr himself on the altar of capitalism to have his message taken seriously.

The movie is factually correct, but the way in which the facts are presented are crafted from an obviously biased perspective. Because of that, Moore ends up blurring the line between documentary and propaganda film.
