Gokseong, or The Wailing (2016) has been staring at me from my Netflix queue for the better part of two years. It came to my attention from correspondence with the academics behind the book Possessed Women, Haunted States: Cultural Tensions in Exorcism Cinema, who seek to catalogue every instance of an exorcism scene in a feature film. At 2.5 hours of running time, it was always daunting to start it, but it is worth the time.
