Regarding the premise of the show, it delivers on ALL the aspects. Well balanced mystery, crime and romance in one with well rounded characters. The leads are surprisingly good considering it's their first attempt. The OST is neither overpowering nor manipulative. Cinematography and computer graphics are really well done, nothing negative to mention here. Plot twists are logical enough. Unveiling of different layers of characters personalities, motives and/or abilities is refreshing and serves as a vessel to the storyline, which gets dark. REALLY DARK. But it's a crime story after all...
So far a 10 from me. I'm dissapointed by the low ratings - the story unfolds at a comfortable pace, it doesn't have to be action packed all the time like other shows to keep you hooked.
