Just amazing. I'm a big fan of korean movies, and this one, and i'm not jocking, is one of the best that i've ever seen. A powerfull message is hiden in the childish appearance of the movie. I watched it with my whole family 'cause we had nothing to watch and we were all shocked by the truth delivered by the scenario. It's really rare to find such a realistic and age-appropriate film that deals with this subject. I highly recommend.
