What does that have to do with Moore's movie? He himself has admitted in interview that it is not a documentary.
The original source I heard was on the car radio while I was driving, so I need to search for that after work tonight.
In the meantime, here's a quick one:

"In describing his work, Moore sometimes calls the film a documentary. Other times he refers to it as an op-ed. He says it's 'just a movie' but then admits he hopes that it will turn the election."
