Same! I used to sympathize with Betty, but she's gotten worse every season. Whereas I used to HATE Peggy, but she's probably one of my favorite characters now.

The character I REALLY hate what they've done with is Harry Crane. He used to be an intelligent, stand-up guy. He cheated on his wife the night Kennedy was elected, but he was drunk and instantly regretted it (once he remembered it when he woke up...). He fought really hard to get his wife back and they seemed to be happy with one another.

Now he's just another sleaze ball--probably the sleaziest of all the guys at the agency, to be honest--and getting a divorce.
