Two recurring messages in many Western speculative fiction and horror stories are that humans are not meant to know certain things or to have certain powers.
Some argue that these themes are baked in to Western philosophy and culture because of the Biblical story of Adam and Eve and their breaking of God's ban of eating of the Tree of Knowledge of Good and Evil.
I don't want to get too much into those arguments. I only bring them up because they are important to this movie's story. Although this movie's story originated in a non-Western environment (it's an adaptation of a Japanese manga) , it still features the questions I mentioned above.
Because I am unfamiliar with the original manga, it's not always clear watching this film what was taken from the original story and what was added/changed/deleted by the American director and producers. I have a sneaking suspicion that the interpretation wasn't very good.
