It was exciting to watch it at first, but after awhile it was just too much frustration after the other... If this was a romcom, I would actually "forgive" the unrealistic plot but this was a crime-suspense-love story so there must be a logic. For all that Kim Mu Yeol does - why he never goes to jail or why the girl (Lee Shi Young) detective is always alone in doing her job and why he is always the one to tag along. The action fights were very well executed, Kim Mu Yeol, was flawless in his fights. I just had very high expectations due to the high ratings. Later on the excitement in the beginning was not the same anymore, it just became unrealistic and the unprofessionalism of the lead detective was just too much for me because after all this is a Police Detective story. Cruel City is much better and the momentum was there.
