This drama is so so so beautifully written. It indeed is about "Life". There isn't a single moment wasted. It'll keep you engaged from the beginning to the end. 'What next?' Is the question that'll always be on your mind. The drama starts off really slow and too much of hassle in the beginning, if you pick up the interest from there then you'll definitely end up watch the whole series if not then you'll probably drop after episode 1.
Each and every character is so unique. They have all acted so well. The actors have put 'Life' to the characters.
The end also isn't shown as the perfect victory by the doctors who fought which makes it even more realistic. However, the ending is perfectly perfect.
Special mention to Mr. Gu's character, that is the whole best thing about the drama. He'll keep you engaged. He'll make you wonder what he is actually.. is he good ? Is he bad?
Hats off to the writer.
Indeed a great one. It deserves more appreciation than it got.
