The story was full of twists and turns, but there were so very, very many names to keep track of! Each bad guy was worse than the last and it seemed like every sentence named at least three people. Lots of corruption, which you get used to seeing in Korean dramas, but this one, by the end of the series, people that had been in prison for serious crimes got out scott-free. That was bothersome to me. There was also a storyline where a young woman had a crush on Ji Hyuk - this went on for multiple episodes, and then she fell off the face of the earth. I would like a season three, with more focus on a specific number of characters, rather than just throwing everything but the kitchen sink in.

I LOVED the relationships between the cops. Lots of humor and heart were put into their storylines. One thing I especially appreciated was the way that Oh Ji Hyuk was written (both in season one and season two). I loved that they didn't have him become stupid over a woman. He always had a plan and the character stayed true to himself throughout.

Special kudos, in my opinion go out to Kim Hyo Kin as Cheon Na Na and Choi Dae Hoon as Cheon Sang Woo. Hyo Kin was brilliant as Na Na, my eyes were trained on her in every scene she was in. I would have liked to see her further lose control at the end, that part felt very rushed. Dae Hoon as Sang Woo. I loved him in Crash Landing on You, and he played a completely different character here. He, too, had a lot of chilling moments. Unfortunately, it wasn't until the end when we got to see a little of his playfulness, and I would have liked to have seen more.

Park Geun Hyung as Jung In Beom as the grandfather - I want to be related to him! I love the respect that Do Chang and his ward had for him. Those scenes were lovely.

I did enjoy watching this show, but I couldn't binge it, because each episode made me a nervous wreck! It was time well-spent.
