Kate Walsh was amazing in the Grey's season. Private Practice was kinda a rocky start for me, though Tim Daly is a lovely spark of romantic interest for Addison
I cannot remermber much about Private Practice of the 1st season but just a feeling that it's supposed to be light, fun and brezzy. Maybe because Addison took off from Seatle to come to LA to pursue the sunny day and the beautiful beach. It was initially dramatic and amusing.
