So, just finished this last night. Great drama, especially if you're a crime fiction enthusiast like myself ^^ On to the review! Story: I really did like the story. It was similar to a lot of mystery dramas in that the lead detective always has something odd and mysterious about him, and he and his squad go off and solve all these cases. All the cases are gripping from start to finish, and let me just tell you now, you will never be able to guess the real conclusion of a case until its over, lol. Especially in earlier episodes, they are astonishingly elaborate, but still, quite fun to follow the development of. Like I mentioned, the lead detective has got his own mysterious history, and the reason why I rated the story not quite as high is because I felt that the ending of his story could have been told better, but who knows, there may be a second season to look forward to. Cast: They were all fab. I liked all the detectives in the special investigations quad, especially Detective Oh (Park Hee Soon). He's just such an entertaining character and his phone ringtone is my LIFE (you will hear it a lot, lol). There were other sort of main characters too, but they weren't present as often. I felt that the victims and criminals used in the different cases were also very good at portraying their roles. There are definitely a few sad moments in this drama, prepare yourself. Music: YES!!! For once I actually thoroughly enjoyed the music in a drama lol. It was memorable and really suited the scenes it was used in. Like really, every time certain songs came on they really added to the atmosphere. 11/10 tbh. Overall: Fab drama, would definitely recommend. The ending might not be the best, but I suppose that's up to your opinion of it as well. SIGGHHH, wish it had more episodes lol.
