I love Grey's Anatomy so was interested to see how this spin off would succeed. I watched season 1 in a couple of sittings and am now enjoying season 2. It is nice to see a group of fortysomethings deal with the problems in their professional lives as well as their love lives.
Obviously Addison was an established character from Grey's Anatomy and was the main reason I started watching this but the other doctors at the practice have engaged my interest too. There are a lot of medical shows on TV right now and this is definitely one of the better ones.
