Peter Florrick is awesome. I can't wait watch him dig up the dirt on Will, so that Alicia can see that everyone is gray, not as white as Will's shiny image has been thus far.
Chris Noth is perfect for this role.
I hope that this isn't the end of Peter/Alicia, simply because angst is fun to watch, especially when there's a bit of sexual tension thrown in. Tolstoy said it best--normal, happy families are boring. Give me the Florricks and conflict any day.
