A piece of advice who is going to watch: Watch it alone LOL, eat popcorn while watching and don't cover eyes with your hands, you will miss some actions. I watched because of Kang Ha-Neul. The story is not bad, but you will have lots of questions after their behaviours. P.S. From the beginning it catches you, you think that you already know what will happen but you have no idea. It makes you more interested. Sometimes I was bored during watching. In conclusion, the movie is not bad but could be better :/
