Yes, I know the purpose of a documentary is to "swerve" the viewer (and at this Moore is one of the best), and I know that there is no truely unbias film/doco/book/whatever. I know Moore claims the film is not a documentary, that's it's simply just "his movie", but that is horse shit. It's portrayed as a documentary everywhere apart from Moore's mouth.
Regardless, I personally don't take "it's his opinion" as a good excuse to blatantly lie and twist truths.
btw, just for the record, I don't mind Moore films. They're generally pretty entertaining, it just annoys me the Moore "followers" who believe automatically everything they say... you know the type, the 16 year old who saw Bowling For Columbine and read Stupid White Men, so now he's a political activist.
