When i saw lee joon ki in and moon chae won the couple that solicited everyone in flower of evil, i decided to watch this drama but from the frame of the story, it was groundless, one team is investigating cases, each episode is independent , the case scenario is not adjusted per episode as it may start at the end of an episode and continue with the another, the recap is a mess.
The first two episodes and the last two episodes can presume everything. Among the storyline, there is many defaults and some good outwork.
first let me start with the good things i noticed, the NCI agents are powerful as team, i liked this profiling method to unveil the criminal, the IT used for tracking, hacking, and extracting information is well mastered, they study the psychological background of the criminal to identify him and his motive for murder which was the trauma the most reason that developed the desire to kill someone in addition to the false believes triggered by a psychological disorder subjected by the trauma.
On the other hand, their cleverness is countered by some dumb decisions that they make or fruitless move that they take which may endanger them like in the last episode so where was the backup knowing that the reaper isn't someone to be taken lightly( i liked his personality btw and how he dazed the authorities exposing their weak points and soften parts).plus there is some technical problem in the montage that some scenes are doubled beside that if they have ended an episode while they won the investigation and cought the criminal, the next episode start anew like nothing happened in the previous one,example when Na young and hyun jun were injured while she was abducted by that criminal who has multiple personality disorder, the next episode, they were sane like nothing happened.
Let go also of the things that has not been sort it out properly in the scripts and others..
Quotes at the end of each investigation were valuable/ the ost were good also.
There was no love story in this drama and that's a dark point also not much to laugh about, only the last episodes can give a bit of a goosebumps but it doesn't last long .
This drama was not a success unfortunately
