This is a fast paced drama from beginning to end. The reason I gave it a lower score is the first 6 or so episodes of stupid cops and prosecutors. Luckily, everyone gets smarter. Jang Tae San is a well written character. I enjoyed most of this drama and was completely satisfied with the ending. Lee Jun Ki is an excellent actor. He went through the gamut of emotions as Jang Tae San and did it well!!! Kim So Yeon is one of my favorite actresses. Her portrayal of Park Jae Kyung was right on. The other actors are good too. That little girl as Soo Jin is too cute. I loved how they had her play Jang Tae San's conscience in some scenes. The music is fine. I might rewatch this in time. I recommend this to people who like thriller/action dramas. Once you get passed the stupid, it is a great drama.
