I think it comes down to how you feel about President Bush. If you like him, you think Moore is an idiot, and you will probably NOT watch the movie. If you don't like him, you think Moore is a genius, and you will probably see the movie.
I will be quite honest....if a person takes their opinion, on the Bush presidency, strictly from this movie, I have serious misgivings about that person's ability to think for themselves.
And besides, it is obvious that the majority of the country felt President Bush was the better of the two men....
