The show is great, when it sticks to human level stories. But in season 3 Dr. Goodwin has become a cartoon character trying to solve a massive, new problem every week.
While other doctors are helping and healing, he manically runs around trying to end things that have plague the world for centuries. He thinks his pathetic shallow and ignorant attempts to "fix" something always works, but it's inevitably followed up by a lesson from the victim he's trying to help.
I literally fast forward when he's on the screen, simply because his stories never interacts with anything else on the show.
