I stopped watching about 2 years ago too. Agree the oldies were soooo much better;
Benton, typical surgeon, no people skills
Doug, eye candy with a great bedside manner!
Dr. Green, most believable doc
Dr. Carter, the longest there ??
Romano, arrogance personified, loved him!
Lukka, loved the accent
Kerry, quite annoying but also likeable
I liked Alex Kingston in it too, thought she played a good part. Carol & Abby were very moany! I didn't get the newer crop of docs at all, Pratt, Neela, Morris etc, they just didn't seem believable as doctors to me.
It was great in its heyday, but its time to go.
