Aunjanue Ellis
Although this character Ann is pretty much a horrible person in my opinion, this actress Aunjanue Ellis played that role to the 100th-1000th degree. This actress talent has no boundaries-she's amazing. The emotional life of this woman, the depth... you just believed her totally as this woman -- her commitment to the character showed. That performance was so strong.
I'm hoping when the Emmy nods come out next year -- she gets a nomination.
Sherri Shepherd was good to but I did still get the sense that playing a dramatic role was new for Sherri.
