First time writing a review, but I really need to do one on this drama (it's surely a little late to do it, never mind). The sytem of notations didn't express well my feeling : i have loved the story, the cast and the music but overall I was disappointed. This drama could have been wonderful, and that's even more frustrating. Mostly one thing has prevented this drama from perfection : the format. It was way too short, the drama really need at least 10 episodes in addition ! I quite like the length of 30 minutes for an ep, they were really intense and thrilling. But overall the story was completely rushed : the romance was rushed, most of the characters had no development except the two heroes, relationships were undeveloped (except between the two heroes). I guess they want to concentrate on the investigation but even this part was completely rushed : the situations were way too quickly explained (it was so hard to follow the story sometimes), links between cases too, and the cases were resolved more and more faster when they were more and more dangerous and complex. Furthermore I wasn't afraid at all of the villains. How could I ? They weren't really present : not a long time on screen, not mentionned a lot, we didn't know a lot about their personality and/or intentions ; it feels like 'little villain' when they weren't at all... It's really the problem of this drama. The story was great : super great characters (good or bad ones ; I loved Xu Xu and Ji Bai they were soooo cool), interesting cases with surprising turn of events and a guiding thread between all of them (so well thought !). The drama was also well shot : great atmosphere (with a good uses of music), and I really like the use of the camera ; and the cast was super great (mostly for the two main actors who were so perfect in their roles). It only needs more development, just way more development... (and that's why my average note of story/cast/music is higher than my overall note) (Another thing which really bother me was the romance : it wasn't at all what the synopsis promises me. I guess in the novel it's more clear that the lead falls for her in first, when here... they just don't have the time ; But finally I never really see him fall in love when I was really waiting for that. It's maybe not that important but I was disapointed. Overall romance in this drama really disapoints me : lack of development for the main couple and you don't really feel that they fell for each other (mostly Ji Bai) and for the secondary couple, wah... no comment). To conclude, this drama was really pleasant to watch, but it leaves me with a sour taste in mouth and the thought that it could have been way much better.
