A veteran detective who is about to retire unfolds a breathtaking psychological warfare with a mysterious man who follows his path while hiding his identity.
The drama shouldn't have been split up into 2 seasons since it was a one big continuous story. This split created a few more problems along the way. Some of the baddies cast members had a clearer split between both seasons, focusing on a few of them each season despite having one grand story. This created some coherency problems and made it feel disjointed. Personal stories, relationships and side characters had an unequal amount of focus between both seasons. A case in point, the ML's daughter/family had only some focus in season 1 while being completely absent from season 2 (aside from 1 flashback) which took away from the ML's character and drive. Especially when his entire character was built on the ghosts haunting him from his past. The focus shift was exactly the opposite with Lee Sung Ah between both seasons. Anyway, enough about jumping between seasons. The cast members brought a good performance especially our leading shadow detective. I really appreciate the production not turning on the beauty mode on for Sung Ah & Joo Hyeon. You can see the pressure and exhaustion their carrier put on them over the years. The cinematography was good for the most parts, especially with scenes involving the detective alone, but there were some dodgy shots here and there. The story was well written with a decent pace to match the suspense. The thriller and intrigue were blended nicely with some nice action scenes. However, the last stretch of the story got a bit weak and disorganized after building up the story for a grand finale. Also, some overdramatized deliveries ended up backfiring, making important scenes less impactful. The introduction of the last episode was good, as well as that dream sequence. His speech about him wanting to stop running while reciting his past was the most memorable moment in the drama. If that wasn't enough, the very last scene was the cherry on top to tie it all up.
