... it's not using it.
It is basically like "House" only instead of being a team that focuses on mysterious illnesses, they specialize in organ transplants.
After seeing one episode, I really did not see much that made me want to see more. It seemed like a cookie cutter show with scenes that you've seen in medical shows over and over again. What makes medical shows interesting is the characters.
There seems to be a lot of characters in this show, but none that seem very interesting. Treat Williams is about as boring as you can get, and there are no real high points in a cast that seems talented based on past shows.
All in all, if you see Heartland, you might like it. But if you haven't seen it, then you have not missed much.
