I've watched all of Moore's documentaries and this one is far and away the best. There's none of the polemical fireworks of Fahrenheit; it's a film that examines people's lives and Moore simply allows lots of space for their stories to be told. This is a very balanced look at the American health care system and is a documentary with optimism and hope despite being very bleak in places. Moore tries really hard I think to talk to American audiences in his films - he frames his issues with wit and a deep sense of wanting things to change. Hopefully, this one will have some effect in America where it is most needed. I've heard that even Republicans have come out of cinemas moved by its message and perhaps a little disturbed by what it has to say about some elements of the American system. The masterstroke of the film is the revelation that Moore secretly paid the medical bills for the wife of his most strident web critic. It is timed perfectly at the end of the film and is a truly moving moment in the film. The fact that Moore moves some people to seemingly despise him for being motivated by a love of his country and filled at the same time with a sense of rage at certain injustices confirms not only that he is doing something right but also warns us about how screwed up people's values are. A film for lovers of truth everywhere.
