Besides all the negative appointments and the low rating, i find this show amazing! Against all odds, it's almost cool as House MD, witch i really loved. Each doctor is amazing, completely different from each other, with very strong personalities. The stories are cool and well made, and the medicine part is so realistic.
There's some negative points, indeed, like the small cast. Will be a very difficult job to the writers to make more than twelve episodes, in my opinion. Each episode revolves around one or two specific cases. We could have one case for each doctor, for example. I think they should cover the personal life of the doctors, too. It's like if nobody got a family, kids, almost unreal.
But overall, it's very enjoyable show. Give it a try before believing in the negative reviews done here.
