It's basically Sherlock but medical. It's not really realistic but it's pretty entertaining and it's also a drama, so there's plenty of captivating scenes involving different characters, their relationships and struggles etc. It's a 4.5/10 at its worst and an 8.5/10 at its best.
I wish ANY of my doctors were this good looking. Especially Cuddy! My wife's cardiologist is a PA, and he's gorgeous. Yes, he's gorgeous, and I'm NOT gay. What a great show. Makes me happy I was out of work in 2011.
