For me it's a toss up between John Stamos and John Liguizamo...couldn't stand either one of them!!
shareI have a many-way tie:
1. Cleo.
2. Abby.
3. Sam Taggart.
4. Dr. Del Amico.
5. Dr. Carter after he goes to Africa--he comes back as a super jerk, and his character never really stops being this way.
6. Dr. Carter's wife(?), played by Thandie Newton.
every new character wasn't in the first 6 seasons except louka and sam
and maybe Neela .
abby irritated me
Eriq that's Eriq with a Q
shareDr Greene's teenage daughter Rachel was really painful to watch. Granted she was a troubled teen, but she was just awful. I remember an episode when Greene's altered Mother mentions the darkness of his ex also being extended to Rachel. She may have been altered, but she was absolutely right. I know the teen character had to exist on the show, but the writing didn't give her any redeeming qualities.
shareFor me:
Abby - downright depressing for her entire time on the show
Tony Gates - Too much non-medical related drama. Learned more about his relationships than his doctor skills
Victor Clemente - what a trainwreck
Memphis Raines: I'm a little tired, a little wired, and I think I deserve a little appreciation!
Clemente.
