A very clever, simmering, at times disturbing, crime drama where one never knows quite what's coming next.
It doesn't have masses of blood, blockbuster style action scenes or romance, but it does have more than its share of shocking moments, an intelligent script, some laughs and what I found to be a gripping story.
I loved the characters; proper villains and a blurring of what makes a good detective. Tested friendships and what seems, at times, blind loyalty from some.
Dong Shik and Joo Won are polar opposites and neither trusts the other at all, for varying reasons that are slowly brought to light as the story grows. They have to work together though and so a relationship of trust/mistrust yo-yos with each episode.
The tragedies in several cast members' pasts are also uncovered and these link characters together in unexpected ways.
Almost everyone looks guilty at some point and the way in which key crime scenes are shown in multiple scenarios, to fit a given character's statement, is brilliant. It also makes it way harder to decide who's done exactly what.
Shin Ha Kyun is excellent in his portrayal of Dong-shik, veering from warm and funny, to maniacal in an instant. His whole face changes when he smiles, but the next minute he can look very scary!
Yeo Jin-goo gives a very understated performance of a character repressing a lot of his thoughts and feelings; no over acting here, thankfully!
The entire cast were great. I particularly felt for Jung Je, such a tormented character, so well played by Choi Dae-hoon. There are some really sycophantic, nasty and loathsome, as well as sweet, caring and strong, characters in this.
A great story with a solid ending.
Oh and I loved the trailing violin music, Bibi's 'Timeless' and gritty song, 'The Night' from Choi Baek-ho; perfect soundtrack.
