This series has an amazing ensemble cast, all individually outstanding actors, who work together brilliantly. The first half of the series was gripping, tense and had a real sense of foreboding about what was to come wrt the Chairman and his meglomaniac control of the hospital. The various subplots, the relationship between the Ye brothers, the budding romance between no Eul and Mr Gu, the under-appreciated Organ donor officer, the whole question of whether Mr. Gu was a decent man or merely duplicitous, were all enthralling and entirely believable. But then it seemed to lose its way. Without wishing to spoil anything, the series ended with NOTHING happening. A minor boardroom skirmish at best and a lot of unfinished storylines. I hope there will be a second series because the first established some fabulous characters and storylines. The series has such potential and such great acting that it would be a shame if it just stops where it did. First time for me to view a Korean drama and I enjoyed how stylish and slick the cinematography was and how unusual the editing is, relative to western tv. Well worth a binge.
