Her character was always making somewhat soft-headed proclamations about being too aggressive in past shows, and was always shot down. Sort of like Clair Kincaid's character was at the end (I found that character insufferable - always there with a liberal rant). The set up for tonight's firing was a comment that for the past few months no one in the office ever listened to her. And for good reason!
I really liked the first ADA, who claimed (I think rightly) he was fired so a woman could get the role, but I did like Jill Hennesy. I also liked the other two women who followed her up; Angie Harmon eventually grew on me, but I think the other one...agggg mindfreeze...was the best. In fact, I've liked all the actors on the show with the exception of the guy who took over as Lenny's partner. I think he's a good actor but he's too heavy--I liked it better when Briscoe was the one who needed to be calmed down.
