The series is interesting, moving, intriguingly depicts criminal cases clearly reflecting the atmosphere and problems of Japan. Sometimes the criminal can be "sniffed out" immediately, sometimes he is discovered late, which adds detective charm to the drama. A big plus are the interesting characters and their personal life threads very delicately portrayed against the background of the criminal cases. Good camera work. Atmospheric music. Great selection of songs. One minus - a green filter that distorts the world and is annoying. All the rest of the production makes up for this shortcoming. A very good crime j-drama.
