Moore uses some nifty editing to emphasize Bush's true character.  For example, in the scenes of my pet goat and his announcement of the war, Moore slows down the footage thereby placing emphasis on Bush's insecurities.  These qualities are often missed in real-time, but ever so important.

If we debate the merit of the film only on facts it's easily for the Repubs to claim that certain facts are left out, or that scenes are taken out of context.  Consider the "haves and have mores" clip.  Repubs claim that it was said at an event that is supposed to be funny.  Both claims are factual.  The Problem is that that sort of humor is disturbing to the "have nots".
