I know my title might sound a little dramatic but it is true. This was one of the first Korean movie's I had ever seen and after that I was hooked. The story is original and beautifully shot. I never understand why people write a synopsis in a review. You can watch the trailer or read what IMDB already has under description. Moving along the movie is great. Good story, drama, fights, and twists. It's on Netflix so catch it while you still can. Stay away from the atrocious American remake. That movie was garbage and a mockery of this Korean classic. Hope this review helps.

A brilliant, brutal and bloody mystery with many twists and turns. The "hallway scene" and the whole final confrontation sequence are unforgettable as is the movie as a whole!

I dont think i'll see any movie like this again in my life maybe with a lot of blood and violence but this? this is heavy yo

Hit me inside of my skull so hard I'm still stunned. Whenever I think about it...No words. YOU GOT TO SEE IT.
