The Closet - Es ruft nach dir

Name a korean horror movie. I've seen it. Where did all the good korean horror from the early 2000s go ? Somehow people thought "The Wailing" was a great movie and now everyone is trying to copy it. Exorcism, Shamanism everywhere. Where did the subtle creeping up your brain horror go ? This movie is like an american exorcism movie. It even has jump scares. It starts rather promising but becomes kinda uncreative quick. I have seen most of this somewhere before, in a better form, in an US movie(Insidious). That's not the kind of horror I want from a korean horror movie. Theres a hundred better US movies with that topic out there. Not impressed at all.
