You may think this is a medical show. It's a medical show like General Hospital was, and remains, a medical show. Not a medical show per 'se, it's a drama about the doctors, patients, administrators, all manor of unsavory types, and public servants who intersect in and around the Knickerbocker Hospital. If things are not really wonderful today, the years surrounding the turn-of-the-century is a worse time - corruption the norm and bigotry accepted and encouraged. All this, plus the medical sciences are still pretty arcane in many ways such as the life expectancy is not yet made it to an average of 50-years.
I do not pretend to be a "deep" reviewer as I've only watched the pilot episode. I do like what I see. The show is a gorgeous time capsule allowing the viewer to glimpse into a late 1800's world with tremendous accuracy and lush cinematography. Each scene is as if it took the better part of a year to craft into a seamless view of a time well past. Oh, the props and the costumes! They're great. Clive Owen is, more or less, spot-on as the plenty mysterious doctor you love to hate. In his role here every crease of his face is as if perfect in bringing this character to fruition. I think we have a possible series for those of us who will miss that recent other great period drama "Boardwalk Empire". An excellent start.
