I have to say, this is the first drama that I watch without skipping or ffw over the boring parts... It's full of action, and even if repetitive at times (hospitals again and again, or the car accidents ) they did use these repetitions wisely to underline the effects of the time/history changes. I did love the characters, not so much the cast, except the main protagonist. She was the only one really acting there. I did not love the music... After watching more than 10 dramas it does feel all the same, I can't tell the difference between the music of one drama to the other.
