I went to see SiCKO yesterday and thought it was stunning. I'm a fan of Michael Moore's other work, but, just like you've heard, this one is really different. And I knew the film is about the American health care system, and I'd seen the trailer (below) and other clips around the Internet, and I saw him on talk shows promoting the film, but I was still stunned in the theater.
As the opening credits started to roll, I noticed that I was anticipating hearing Michael's voice; I really enjoy that he narrates his films, and I trust his voice. I think that's because Bowling for Columbine and, even more, Fahrenheit 9/11 were released at times when I really needed to hear the truth and felt like I couldn't find it anywhere.
There's a point in the middle of the film that addresses the health care issue in a bit of an existential way, and I was completely taken back by it. Yes, I cried. And I laughed at other places, too, so I guess I have to say it: I laughed, I cried. It was a bit difficult to watch from the perspective of a former expatriate - it's hard to not envy those lucky enough to have American citizenship and lucky enough to live outside of the States. I was wishing that was still me. You'll love the film. I can't wait to see it again.
