I highly recommend checking this movie out. You can watch Korean movies with English subtitles at Cinus in Myeongdong and Gangnam.
I'm still peeved at Cinus's poor advertisement for English subtitled movies. In fact, they even write IN KOREAN the fact that there are English subtitles for the movie. They don't provide any English title and it appears they don't even have much in the way of movie times. They've made this resource almost inaccessible. But, now that you know, please head down to Gangnam and Myeongdong to check out awesome Korean movies!
