I was able to perfectly understand Dark, but not this movie. I love the folklore stories but, the thing that makes the horror a huge success is the possibility that is a thing that actually might happen. In this movie you are going to see great especial effects, but also a complicated set of rules to follow, a song, 7 laws, a complicated artefact, possession, zombies, cannibalism, human mind control, animal mind control... The first half of the movie is great. After that is a down fall from there. I put six for the effort, because doesn't makes any sense. Lacking motivation and conduct thread. Sometimes less is more.
