Good movie but grossly overrated

Simple and well acted, it has tension enough to knot the stomach.

The biggest problem with this movie is it’s a little better than you think it might be, which somehow makes it worse. As in, it takes itself a bit too seriously, which makes most of the movie feel kind of dull.

This is a dark and sometimes deeply uncomfortable drama

Lee Byung-hun is a kick ass. his face, his voice, the way he walks, the way he stares. im a fan of thriller/slasher/horror movies. and yet this one wowed me away. my blood pressure went up after watching this movie. i was in a mess, at the edge of the seat most of the times, i felt like screaming and punching someone. this movie gave me a whirlpool of emotions. it gives you an insight of what goes around in a killer's mind and the victim. audience gets to see a killer being hunted. this movie is beautiful. it's gory, yes, but it's beautiful.

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.

I absolutely don't understand both the IMDb score and those reviews here. How can somebody find this film good is beyond me. I must admit the beginning looked fairly ok, punishing sins of the murderer could have led to interesting situations and psychology, but the whole point was destroyed by every of the characters acting unbelievably stupid and/or reckless and by ignoring basic rules of what is and isn't possible.The murderer is outright invincible, he has broken wrist and cut off achilles tendon and yet nobody can resist him. He wouldn't cease killing everybody in range although this must have brought unwanted heat on him. The special agent doesn't care about casualities although he tortures the murderer in the name of his wife (or fianceé?), which is totally inconsistent and makes no sense. The police is totally inept and don't get me started on the victims behavior.After killing the first "release" the whole plot became ridiculous and messy, the violence pointless and as the motivations and deeds of the characters were revealed as fantastic, stupid and inconsistent, I stopped caring about the movie completely and was just waiting for the end, which came way slower than I hoped for. All in all, huge dissapointment.
