I've been watching M*A*S*H on Netflix, starting with the 1st season. The more I watch, I am convinced of several things.
First and foremost, that replacing Burns with Winchester was absolutely the right move. Burns was a weasel, and more importantly, never had any hope of being a worthy opponent of Hawkeye and Trapper.
For similar reasons, I like Potter over Blake. Henry was a decent guy, and tried to do the right thing, but was far too much of a pushover. Sherman still brought a heaping dose of common sense and pragmatism, but wasn't easily snowed.
Thirdly, Radar is *far* from the innocent lad some folks think he is. He may not be wise in the ways of women, but he is a slick operator when it comes to Army bureaucracy.
