Which introduced characters didn't work for you?
Which characters came into the show that you thought lowered the great quality it kicked off with? For me:
Will Bailey, could be that he was the replacement Sam of sorts but I just found him to dry especially in scenes with Toby it's like the same character talking to himself at times. At least they shipped him over to Bob. I do like the actor in Big Bang Theory though.
Deborah Fiderer, not so much that I had an issue with her just that Mrs. Landingham was a tough act to follow.
Tinkerbell, ARGH fingernails down a blackboard! Not really sure what the hell her job was? Was she CJ's replacement as press secretary? Toby still seemed to cover some of that job. If CJ were qualified to become CoS would Carol have been qualified enough to move up to press secretary?
I also though the first lady taking on a bigger role was a problem. OK in small doses only.
