Its not crazy, but its not that interesting either, unless you are of perception that Moore never sacrifices accuracy for storytelling. Its really more biographical than critical, as they spend way too long pointing out that he's rich.

It's cute how people on the right still to this day think that Moore is some patron saint of liberalism and that anyone remotely to the left of center worships him like some obese deity that has fallen from heaven and that if you say anything bad about him it SHATTERS THE WORLD AND BLOWS YOUR MIND. It's also cute how they keep trying to obscure the issues he raises by invoking all sorts of tangential issues and strawmen to make HIM look bad instead of actually examining the questions he raises.
