If you didn't know who Michael Moore was and you watched it for the first time, it's very entertaining and informative. It's also very in your face and a different style of doc filmmakers.

He sits very strongly to the left and it's this extreme that hurts him in the end. Just watch this doc, none of his others and you're set.
