I think Ann is incredible. Especially how she helped Jana with her accident. Externals don't matter, she's beautiful inside.
Jana/Grego were interchangeable for me. Neither had a personality and both swung with the breeze. Meh.
Joan was another lovely personality. Mature and serene, hope that wasn't just Botox. Seriously, if it wasn't for the panty thing, she would be perfect. Who does that at a dinner party when you don't know the host that well?
Roxy was an arrogant, vain, troublemaker. Swollen with self importance, I had no respect for her. She was the root of every gossipy story, what a horrendous individual.
Kara was an insecure, pretentious, judgmental toothpick. She did speak out of turn but I would have been so grossed out if I had found someone's panties after I threw a very, elegant, thoughtful dinner party. The ladies never gave her a fair shake. She is an odd duck and they let her feel like an outsider from the start. I don't like Kara's personality but I do like that she stuck up for herself and played the villian well.
If there is a Season 2, we need more interesting housewives.
