I wasn't sure about watching this movie at first. Asian movies tend to have a higher rating in general. But I gave this movie a shot. The movie starts out as a cutesy family story. Then it turns into a mystery with the brother's kidnapping. Then it turns a little sinister horror-like with eerie sounds coming from the closed room. Then with the brother's return and strange ways, it gives it an action and crime drama twist. Then with the big reveal you discover it is actually a psychological thriller. You then notice that you have over half an hour more of the movie to go after what you think is the big reveal. And then when you start wondering what else is left to see in the movie, tragedy strikes and it is heartbreaking. Brilliant film making. Now I want to watch more South Korean movies!
