Both are horror genre.

One is an anthology series and another is a movie

Both are SERIOUS horrors, not easy-going or light horror.

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.

Both horror stories that feature shamanistic rites and supernatural beliefs. One is to cast out a demon from a human body while the other is to prevent (the death of) an unmarried guy from becoming a vengeful ghost.

Both are horror films that tackle religious themes and doctrine. As the main characters delve deeper, they second guess who and what is truly evil.
