I watched last season and I couldnt wait for this season to start.
I must say that I really enjoy the show. last season, things got a little crazy, and how they got out of the dilemmas they were in were even crazier, but enjoyable and interesting to watch nonetheless.
In the first season, the show started off with one partner (Macnamara) being the straight laced "good" guy, the guy with morals, etc. The other doctor was the "bad" guy, the womanizer, the morally challenged individual. Toward the end of the season, those two labels were left behind and left viewers questioning how these characters were going to proceed. This year, it almost seems as though the 2 main characters are switching parts.
I find it interesting. I also find the backdrop interesting, e.g. the absolute vein qualities that people possess and such, the fact that these guys have more money than anything and yet they are unhappy. Quite a lot of themes going on.
For those who havent watched it, tryit, you'll like it.
