I loved this movie! Definitely one of my favorites. Lee Min Ki and Son Ye Jin made this wonderful. I don't think I could imagine any other actors playing their part. It wasn't too scary, but I don't think it was lacking. I feel like if they had made the movie scarier, or even less scary, it would have taken away from the story. I'm glad they didn't make the scare factor overpower the storyline like a lot a American horror movies do. 10/10; would watch again. I definitely recommend.
