This police movie is quite classic in the topics it approaches: corruption in the police force, undercover investigations, drug crimes,...Its plot does not stand out among the existing movies in that genre and suffers from some pacing issues.

The main default of the film is the grey message that it is conveying. The ending was quite unsatisfactory to me, as I'm left to wonder what was the morale of the show. A story does not always require to have deep meaning but as the characters were almost having philosophical discussion on what being in the police workforce entails, the conclusion felts a bit like a cop-out.

The main cast (-an entirely masculine one with a lot of veterans) deliver solid performances. The relationship between the two leads is incredibly well depicted, making us doubts a lot the intentions of the characters. I wish the story had offered even more options to the actors to act their hearts out, because I'm sure they can show even more than what they did with the material given.

The film-making and directing are strong. There is clearly a "film noir" aspiration in the aesthetics and storytelling of the movie making some of the scenes really appealing to the viewer's eyes. On another side, the OST did not stand out to me.

I would recommend this to people loving Choi Woo Shik or Jo Jin Woong and/or who are looking for a police movie with high production value. It is still a pretty flawed picture in terms of story, pacing and ending, so you will not miss much skipping this one out.
