Anybody you can play the part of a nasty B* the way she did last season, isn't acting. She was so "good" at it, I could hardly watch the show and haven't watched a single repeat.
Let her stick with her party which is rife with antisemites... How stupid can she get?
While I didn't see it last season, I agree with you.
When she was whining to the psychiatrist about Tony, and he told her to leave, but not take any of the 'spoils', I think she was well acquainted with the self-deception needed to ignore the advice. I don't see that as acting.
