This is definitely a movie for a mature audience since there are excessive violence and blood.

The story centres itself around the three officers who are chasing the same culprit, Kim Gwang II. As already provided in the summary, the plot is mainly focused on the conflict of interest that these three officers face in their own jurisprudence. In that, the characters are saved from great acting by senior actors in the industry, yet at a closer look is a little flat in its execution. There was definitely more back table politics than on-the-field action scenes in this that if included in the plot, would have made the whole viewing experience much more interesting.

The biggest criticism of its execution is obviously on the characterization of Kim Gwang II, since he's the most interesting character in the story yet given very little to take away from. Interesting details that should have been included to add more depth into his killing rampage would be his motive, background and a deeper look at his familial-political influence.

Park Hee Soon, Jang Dong-Gun and Kim Myung Min are senior actors who did really well in their roles, except the actor who plays Chae Yi Do should go easy with his blowing cigarette off people's faces behaviour because it gets really annoying. There are also so many curse words thrown around which are probably meant to show some realism, but in my opinion, only further accentuates the weakness on the part of the scriptwriter.

Lee Jong Suk is definitely a show-stealer in this because his smirks are creepy and his cold-blood murder are incredibly terrifying to watch. It would be great if he has more chance in the future to play more antagonist character because he executes it so damn convincingly. A fantastic deviation from his usual cute, puppy-like main leads characters.

Definitely watch this for Lee Jong Suk, if not for anyone else :)
