Both are set in a fantasy world where the zombie apocalypse is eminent. Both dramas starts by showing how the outbreak supposedly started and how the people around them adapt to the situation. The origin of the pathogen is different but it still has the same effect. Not your typical zombie shows.

Like the Japanese Ballad of Narayama, Kim Ki-young’s Goryeojang (???) envisages a world in which the old are expected to sacrifice themselves for the young, but unlike either Keisuke Kinoshita or the later Shohei Imamura, Kim struggles to find nobility in adherence to such a cruel and inhuman tradition.

Both horror films go around a possession case set in a village/rural area, either from Thailand or South Korea. As The Medium's producer, Na Hong Jin's work constitutes a big force of influence, making it obvious its resemblance with The Wailing.
