I watched it because I saw there was already Season 2 and assumed it must have been good.
Lead Actor & Actress:
The male lead Jang Hyuk is one of the actor I like since I been watching his dramas since I was young, so I was excited to watch but the actress Lee Ha na is one of actress I tried to avoided watching as lead because of her kind of awkward acting but surprisingly she did her job pretty well in this drama and she suited her character. But character Jang Hyuk was playing kind of annoyed me for some reasons. I feel he should listens more to female lead, not always act tough and get in fights all the time but his character does improved in later eps.
Kim Jae Wook did an amazing job as psycho character. And he was pretty handsome which is a bonus for us.
Storyline:
It was quite an interesting concept and loves the cases they had in the drama but somehow in later eps I got bored. I feel like I was more interested in those small cases rather than finding out who the actually killer was because I feel like it was pretty obvious who is actual killer is. When they concentrated more on catching that killer I lost interest but I did watched till the end.
Sometimes I feel like cops in the drama were too slow and I got so frustrated watching when they dont move quick enough and just standing there or started talking with each other and I be there like:"Hey she/he is going to die....Stop fighting..Go and save them". Overall the drama was okay and I finished till the end but is not the best crime drama I ever watched. The acting was great but some of the characters were annoying or useless. I dont hate the drama but I dont really recommend anyone to watch it unless you have too much time and love the leads.
OST:
I dont think I even remember any songs from the dramas.
