How has she regressed so severely as an actress?
I realize "Scream Queens" isn't the type of show where it is supposed to show off one's acting skills due to the quality and overall campy nature of the show itself, but even the content she is given, the execution is so poor.
She is miscast as Chanel #5. Her acting is just so bad, wooden, and amateur. Everything she says, it sounds so poorly exasperated and high school level. She used to be so good -- now, it's all just bad.
