Oh, YES she is. She's gone from normal girl next door providing sunshine and friendship to the guys to an obnoxious drunk who sleeps around and is rude to everyone. The only characters I really care about are Leonard, Bernadette, Sheldon's mother and Howard. I just find the other characters... repulsive. Especially Amy - she was repeatedly rude to Wil Wheaton, and it's WIL who's forced to apologize? Can't understand why she's fandom's darling.
