Sicko (2007)

Easily the best thing Moore's ever done, and the closest to a real documentary, he refrains from falsely or unsubstantiated attack (which weakened a lot of the entertaining, important things about Bowling for Columbine, and was essentially all Fahrenheit 9/11 WAS), and devotes about 10 whole seconds to self-congradulations, at the very end, as an afterthought (as opposed to An Inconvenient Truth, another documentary about a very important issue delivered by a divisive Liberal, in which an important issue was clouded by how self-congraduatory and self-obsessed Gore was). An important, downbeat topic handled with Moore's usual ironic wit, but, as mentioned, with a lot less aggrandizing and unsubstantiated finger-pointing than Moore is known for using. Amazing movie though, and, along with The Power of Nightmares, you might owe it to yourself to see this film.
