Well,

Rating: Null/10 (28 October 2004)

as a German-born half-korean, I can only laugh at airheads like TDeath further down here. That German wants to complain about poor dialogues? Do you even understand Korean? Can you read hangul? Or did you just go by the subtitles? Please elaborate! Is it the movie's, the director's, or the writer's mistake that the English subtitles are piss-poor?
No, I don't think so. That movie is brilliantly written, the setting and the acting are fantastic, as are the plot and all those little twists and turns in the storyline. Once you realize why the protagonist had been kept imprisoned for 15 years, you are just invited to join the ride, because then you realize that it's not just your plain old revenge movie, but one with a twist, namely *SPOILER* that the true reason for the revenge starts at the same time as the revenge does and that the 15 years before were just a setup. A Masterpiece.
