I liked this series very much. There were none of those typical "filler scenes". Everything was important. I especially liked the special effects when Kang San uses his powers and the friendship between him and Dong Joo.
The plot is very typical for a Korean TV series. A sardistic antagonist, a big political corruption scandal, the police are useless at the beginning but the big hero at the end. The main characters harmonise well.
Overall, it was a very good thriller. For me, it is not a drama because there is no love story. The series was exciting and I think it has repeat potential.
Careful: spoilers!


The only criticism for me is Myung Seok. He was at a crossroad when he planted the wiretap. I would have liked to see the betrayal of this family. Because now he has exploited the weakness of his brothers for his own selfish goal. That, to me, is typical of Koean television. I liked the idea of him getting on the good side and staying with Dong Joo and Kang San.
