"I'm not exactly sure WHAT Fosca needs to do to make you care about her, view her as sympathetic and lovely, instead of controlling and pathetic."
I don't want to see Fosca sympathetic and lovely. What's the point of the show if she's played that way? That was one of the problems I had with the CSC production. Fosca seemed just very mildly depressed, basically pretty nice, and simply in need of a slight makeover to look like Giorgio's attractive if somewhat older wife.
