This movie will have you grow hairs on your butt. (For those who don't know, the Korean saying is, "If you laugh when you cry, you'll grow hairs on your butt/butthole.") Cha Tae Hyun is amazing, as usual, and brings life and depth to his character. The ghosts are quirky, and annoying at first, but they grow on you, and the ending will have you exit the movie with a happy sigh. For those worried about the horror factor, there is absolutely no scary scenes in the movie. In fact, you will most likely be laughing the entire way through. I definitely recommend it for everyone, even for those who don't get toilet humor (after all, you can't really have a Korean comedy without some toilet humor). There's not much else I can say without spoiling it. Please watch it. You won't regret it. Cheers!
