My UO? I actually didn't mind AT. I think he got better as time went on and was not bad on PP. I think a lot of the problem was (from things I've read) that they had him as mini-Blair as a kid then rapidly made him Todd Jr. Which may not have worked. But opposite KdP and RH, he was tolerable.
I am with you all on Marty. She worked short term, for that one story, but to continually try to bring her back and make her be in relationships with the Todds (not quite going there with RH but rapemance with TSJ) was just wrong. And Cole? Yeah, can't say I was sorry to see him go over the cliff in PC. Hope it was wrong to kill, but Cole should have never been,
