This is one of the most captivating films I've seen in a while, and certainly the best vengeance movie by far! It is emotional and heart wrenching, combined with chilling horror and nail biting suspense. Beautifully filmed, every scene is masterfully done. It is a fantastic story of revenge, but also a love story. Both Lee Byung-hun and Choi Min-sik are brilliant in their respective roles. (Choi Min-sik is just so incredibly talented!). This is one of those films you simply have to experience for yourself, as no review can possibly do it justice - it is simply one of the most incredible, amazing films! Be warned, though, some scenes are really brutal and gory.

It's shocking, bloody, brutal and more than a little crazy. It's also brilliant! Know that old Klingon proverb? Well this one is freezing, an ultimate revenge flick!

It started out really good with suspense and scares, then it was getting repetitive and boring. The officer just kept torturing the killer and letting him go. There was no reason why either the murderer was killing these women or why the hero was a murderer later on. It does have some cool action scenes, but goes on too long and goes in circles. We don't know the motive of the characters very well.

What a ride! And I enjoyed most of it for sure!This movie is tough to watch. Not because it is a bad movie, but because it is way too graphical. I'm not talking about most of the beating, gore, torture and whatsoever, because that I can endure, but to watch that one perverted Kyung-chul living and doing what he does was sickening to me (props to actor Min-sik Choi for his performance). And that's the whole plot! That's why the movie focus so much on Kyung-chul! Because it tries to make the audience to feel like Soo-hyeon; to want revenge too. Some acts are way over the top and I kinda disliked it. You see someone take a huge beating, I mean, HUGE, and the other day he's walking around like he just fell out of the stairs. I'm not sure about that.Overall, a fine movie about revenge, but might be way too much to watch for a day.
