Looking back through the thread, I see a lot of people mentioning the greatness of Dewey Crowe, which I agree with. I was surprised to learn that the guy playing him is Australian - he had a pretty credible white trash Appalachia accent.
I really, really wish Dewey Crowe had survived at the end. He was more hapless than evil. As someone said, he wasn't half the bad-ass criminal he thought he was. Raylan staring him down and slamming is nose into the steering wheel is one of my favorite scenes of the whole show.
