Brutally profound
15 September 2010 | by See all my reviews

Just came back from the TIFF 10 screening of the UNCUT version of this film, and after reading the very first review posted here, I feel somewhat compelled to leave a short comment.

the movie is about revenge. a woman is murdered by a serial killer, the woman's soon-to-be husband, who happens be a highly trained special agent, takes revenge on the serial killer in some of the most gruesome ways ever presented on film.

The "TAKEN"-esque plot is fairly straight forward and even predictable at times, for some people, this unfortunately exposes the violence and turns it into a dominating theme, hence remarks of it being mindless and unnecessary are brought up.

But fans of this genre can easily see past the violence, and be drawn back to the noir nature of the film with each passing violence "segement", in the end, you can feel the main character's will for revenge, and that simply transcends the violence, and ultimately turns the film into an imaginative commentary on the human condition.

the film would also remind you of classic Fincher films, namely se7en, however, the theatrical construction of plot is a signature Ji Woon Kim style, the mise-en-scene, the soundtrack, you see it in every single film of his, especially bittersweet life.

after watching this film I found myself immediately comparing it to another masterpiece sympathy for mr.vengeance, so for those of you who have seen chan wook park's revenge trilogy and loved it, you should find time to see this film.
