The slate article above gives another view as to why this 'work' is not a documentary and why moore is clearly just a slime ball as noted above:

"So I know, thanks, before you tell me, that a documentary must have a "POV" or point of view and that it must also impose a narrative line. But if you leave out absolutely everything that might give your "narrative" a problem and throw in any old rubbish that might support it, and you don't even care that one bit of that rubbish flatly contradicts the next bit, and you give no chance to those who might differ, then you have betrayed your craft. If you flatter and fawn upon your potential audience, I might add, you are patronizing them and insulting them. By the same token, if I write an article and I quote somebody and for space reasons put in an ellipsis like this (…), I swear on my children that I am not leaving out anything that, if quoted in full, would alter the original meaning or its significance. Those who violate this pact with readers or viewers are to be despised. At no point does Michael Moore make the smallest effort to be objective. At no moment does he pass up the chance of a cheap sneer or a jeer. He pitilessly focuses his camera, for minutes after he should have turned it off, on a distraught and bereaved mother whose grief we have already shared. (But then, this is the guy who thought it so clever and amusing to catch Charlton Heston, in Bowling for Columbine, at the onset of his senile dementia.) Such courage."
