We rented the first season, and stayed up too late watching the first four episodes (we had to get up early or we would have watched the fifth episode on the disc). And then when the second disc arrived we pretty much watched it in one sitting (four more episodes). I guess you can say we like it, a lot.
I know that there have been people on my friend's page who talked about it, but when you have no reference, it is hard to get it. And on some level I much prefer watching series on DVD – I hate cliff hangers that last for months at a time. And yes I am aware of the big drama going on in season 3 – there was an article in the WSJ about it.
I really like the characters, and the actors who portray them. The story lines are good, although somewhat predictable. I mean I guess it goes without saying that if you are going to do a medical drama about doctors, someone is going to end up with VD and everyone is going to find out. Oh, and the music rocks!
Hopefully the second season will arrive soon.
