The Wailing" has echoes of "The Exorcist," but it is often even bleaker than that 1973 horror classic, as in a scene in which a Catholic priest tells Jong-gu, "The church cannot help you." By this time, I was so invested with Jong-gu and his family that as the suspense, violence and worse ratcheted up, I was not merely scared, but heartbroken. An overly literal bit of business at the end slightly undermines the film. As a whole, though, "The Wailing" is the hard stuff. Handle with care.
