This drama was hands down the worst portrayal of police force I've ever seen. They were unbelievably bad at their job, even for 'police' drama standards. This is the most important aspect the drama needed to nail but failed to do so and resulted in a lukewarm detective/thriller drama. Both Soo Young's backstory and the main villain were lame and disappointing. The only redeeming quality was its cast, specifically the main cast, other than that the drama is straight up a failure. Not even Jang Hyuk contribution helped it. Speaking of which, Jang Hyuk looking like professor Snape in the poster lol.
