Morgan Spurlock is such a likable guy that it's so hard to do anything but enjoy any of his films (or tv shows for that matter). While he sets out with an unrealistic goal (of finding Bin Laden when no one else has been able to do so), he uses humor and his great personality to keep you reeled in for the entire film. His interactions with people around the world and the lessons he learns via his visits are essentially the center point of the film.
However, the film does have one negative point. Spurlock claims he's finding Osama to make the world better for his soon to be born child, yet he's risking his life in some of the world's most dangerous places to do so. If he had been killed, seriously injured or kidnapped during all of this, it would have been an even bigger loss to his child than for Osama to still be hiding out somewhere. It's being a bit picky, but it's still a point to look at.
