Let us say that is true, which we can't really. Moore's perspective is far from unreliable. His movies' main purpose is that which you say he does not do: convey the truth. That is a lie: George Bush has lied, Rumsfeld has lied and all those associated with them have lied. Michael Moore has for once exposed the truth. As for the clever editing, do you think this movie would have been so recognized and would have reached such an audience if it was simply a Hollywood B production.
