This century's Barbara Stanwyck
I'm really only familiar with her work on SVU,so my opinion is,by definition,limited and probably somewhat biased.Still,take it for whatever it happens to be worth.
Initially,she came across as a first-class virago.A martinet,a monumental egotist,a back-stabber,and the kind who would pass off all of her mistakes onto subordinates,and take the credit for their achievements.This is the kind who survives in a beauracracy.And she did that part so very well.Dripping with venom,vicious,and a real man-eater.The kind who would emasculate a guy just to see how sharp her knife is.Well,after all,somebody has to be the villain.In comparison,we had the chance to see the female D.A.'s as sympathetic heroines.
Well,now she's moved up to the bench.And,seeing as how her pervue has changed,she's seemed to have mellowed a tiny bit.
My guess is that ,after all,someone has to play these parts.And she does it so well.
