The movie is violent, graphic, disturbing and yet borders on perfect. Behind the violence and graphic nature is that fantasy, that desire, to see a monster facing another monster and the battle waged in a cat and dog revenge masterpiece. The storyline is one taken from so many movies but with the spin of the hero becoming so much of an anti-hero that he makes the villain look like the victim is impressive. It's a literal tour de force, with two of Korea's best modern day actors and two that could rival any Hollywood "A-lister". Watch this movie if you can, just be prepared for the stomach turning, nerve wracking, twists and turns of a very disturbing movie. This movie is an underrated gem and one that should be on many top 5 lists but isn't because it's Korean market and not Hollywood.
