This series was exciting and involving. Usually I don't like medical dramas but this one was exciting and the medical parts are well integrated into the story and action. A doctor who treats criminals outside the hospital. It is fun to see him improvise. There is a love story and pretty interesting characters both good and bad. An heiress is wrongfully kept in a coma. And the doctor helps her wake up. Quite suspenseful.
The cast is great. This series doesn't depend on Kim Tae Hee's acting so much. But she is actually quite good here as the sleeping beauty turned vengeful chaebol heiress. Actually sided with her in her revenge. Her character gets better and better in the show. Joo Won as the gang doctor is good, although he isn't handsome he looks earnest and convincing. And his forgiveness thing was so sanctimonious.
In a good series like this the supporting cast are watchable. Can't help but like the wicked half brother and the beautiful sister in law who I have found likeable in other shows Jo Hyun Jae and Chae Jung An.
Some reviewers did not like this series that much which is why I did not watch it for a while. Turned out it was quite enjoyable with characters that don't irritate, satisfying feel good resolutions and a fast moving story.
