I am quite a fan for medical stories. The sheer mixture between the ethical problems that we outsiders of hospitals simply love to forget (see Covid and hospitals) is always good for interesting story lines. And with Dr. John it is the same. The background of the question about ethics of medicine and the questions of euthanasia are new to me in this genre, but played without the pathos other stories have.
The players are very good and tho the story is tending to lots of tears in the later episodes, its a joy to follow the series.
So, for the cold and wet season it might be a great choice.
Btw. the only manko ALL asian medical series seem to have is to see feminine workers in hospitals on high heels. Nobody would wear high heels in a hospital.
