Complicated! The movie should have told me what the monsters are, where they came from, why did they come ?? I imagined the whole time it was the final judgment, god's apocalypse, but that also would not make sense. If the ending was "we will not show the monster why else would you kill yourself" would be much better! Everything goes without explanation. Despite this, the movie is good and the note is 7. I just looked because it was hype.
