Okay... I just read through the thread and I thought I'd add a few things.
Firstly, Sheyne, I also liked Dead Poet's Society. A bit cheasy at times, but thoughtful and touching most of the time.
And, I have to agree with RT and Sheyne (as well as Leslie, Barb, Juan and Julie too I believe) regarding Michael M. I really liked both Bowling and F-911. Yes, he's dramatic and sometimes over the top, but isn't that the point? He clearly feels strongly about both topics and thus explores them passionately in both movies. If the movies had just been him being calm and quiet, sitting on his couch discussing his POV unenthusiastically into the camera, would that have been better? Certainly not, in my opinion. And he doesn't just put his own thoughts, emotions and reactions into the films, he also includes statistics, actual footage..etc. I don't think they or he make liberals look bad - I think they make them look passionate and driven. BTW, your posts are so insightful, RT, I love them. It's certainly not hard to tell you're a writer.
Lastly, you have all brought up some great films. One that I think people should see: The Sea Inside (Mar adentro): The real-life story of Spaniard Ramon Sampedro, who fought a 30 year campaign in favor of euthanasia and his own right to die. Beautifully done, just beautiful. And so moving.
