Saw how high the ratings for this drama was on here and decided to watch it and I have to say this drama is such a MASTERPIECE I mostly do not watch noir or super violent dramas but this drama had me on the edge of my seat for every episode with its plot twists and cliff hangers! At first, the drama is confusing but I recommend people to watch it and stick it through the very first episodes. This was the first time I saw all of the cast except Nam Gyu Ri in 49 Days and everyone's acting was exceptional especially Jung Kyung Ho. He has got to be the baddest gangster ever. His acting is superb and flawless, conveying different types of emotions which always pulled at my heart. Truly one of SK's finest actors! Every character was given so much depth and dimensions. My favorite characters besides Doctor's Son was Jin Sook, Soo and Safari. I was disappointed at the lack of scenes for our leading couple and how the ending was played out. Needless to say, the drama is still wonderful and great despite the ending. I will definitely miss this drama. It has rose to one of my top dramas of all time!
