after and i watch the film . i think and why the heck be this film such a high success in the korean box office . even think the movie have a clever or unusal scenario and the act wasn not that good and the character weren not very interesting . for a korean movie . i like the fighting scene . if you want to watch a film without thinking and this be the film for you . but i get to admit . the film be kind of childish . 6/10 .
