Only Rain and Kim Bum could pull off this bromance and make this drama shine... the main romance otherwise was kind of lackluster, but the bromance more than made up for it. Liked the concept overall of certain doctors being so dedicated that even as ghosts they cannot leave their life's work of saving people, and a passionate but jaded doctor as well as an inexperienced but idealistic newbie coming to a middlepoint to cooperate and save lives. It was also nice that the antagonist bad doctors weren't just one dimensionally evil for no reason from the beginning, rather they lost that passion over the years as they had to be realistic to keep their careers; the "bad" doctors also come around and help the younger passionate doctors when they can do it. Overall the plot didn't drag, which is amazing for a medical drama that focuses on hospital politics (by the end they usually have to play out politics that viewer's aren't interested in anymore, but in this show it really never dragged). Could've done with a little less Uee/Rain melo scenes, those were the only ones I 2xed or fast forwarded.
