Saw this on the weekend, along with lots of other people if the box-office takings are to be believed. It’s pretty much what you’d expect from Michael Moore: one-sided and simplistic, but what it does it does very well. I’m sure there are hundreds of commentaries online already, so I won’t add to the noise, but I would recommend seeing it.
It’s scary how funny much of it was, you really don’t have to do anything special to make Bush look like an idiot.
