For many decades - and this was reinforced by the broadcast networks' standards-and-practices department - bad guys on TV had to get their comeuppance, and good guys had to be brave and true and unconflicted. Those were the laws of the business.

TV is designed to keep characters in place for years on end. The best example is 'M*A*S*H:' You have a three-year police action in Korea, and they stretched that out to eleven seasons. It was a great show, but when you think about it, a weird unreality overtakes a television series. You see the actors age, and yet the characters don't.

I'm very glad people love 'Breaking Bad,' but the harder character to write is the good character that's as interesting and as engaging as the bad guy.
