Korean cinema produces highlights that quite a lot of people are not aware of. Landing Steven Yeun (who's internationally known) in one of the lead roles might help change that. But just because there is "Hollywood" star in this, does not make this a Hollywood movie or a movie that is easy to digest. And I'm not trying to make a judgement here.
If you want to, you can call it a "warning". A warning because the pacing here is quite slow. And it is rather character driven with a difficult to define goal or theme. The latter is only really true in the beginning and of course the director has a clear idea of where he wants to go or where the characters have to be. Very low key, but still high on drama and mystery. The movie dares you to make your own conclusions but also gives you hints, not facts. And we are left wondering a couple of things. Very weird indeed, but also very good
