Same reaction here. I really liked Joan of Arcadia; didn't watch it first-run but it was recommended to me. Only seen Season 1 so far.
I stopped watching Joan of Arcadia at the beginning of season 2 because the concept was being watered down. Then recently, I got a hold of the last two episodes where Joan met a guy who could also talk to God but was up to no good. Those episodes made me wish the show had continued. I would have been back.
Is that like playing mentally challenged? "Everybody knows you never go full homo. You went full homo, man."
She got her start on a soap opera. Which is last thing I saw her in. Could be she likes the part or the people she's going to work with.
