First off, i'm a big fan of hospital dramas. I like the thrill of watching doctors save patients lives. But not all medical drama are as exciting and thrilling as this one. The comedy, tear-jerker episodes, and romance are all well blended together. Watching O.R. episodes made me sit at the edge of my chair. All characters were very well portrayed by the actors especially Kim Sa Bu. His kind and compassionate heart not only goes out to his patients but also to all his staff as well, it made me fall in love with the drama. Each episode contains different stories of patients and hospital staff, and it will make you cry a river. I also like how they unfold the conflicts and revelations of characters, i think its very unique.
Overall, i think this is one of the best medical drama. I would highly recommend it.
