It lacks depth in its story telling and emotions, there seems to be lacking in the movie, its like a food with all ingredients but still taste bland. CG Effects are not that great for a movie. Jo In Sung is great but still Nam Joo Hyuk needs to improve his acting skills, he is not that bad here but his expressions needs a lot of training. Seol Hyun, its my first time seen her act and she was good in here. There were some great moments like almost heart-wrenching but fails for it always felt rushed. Over-all its just a movie to watch if you're bored.
