I watched this movie with my English class for Halloween and we discussed the theme and the events going on in the story. Most of us were kind of confused because there were so many things that could be explained better in this movie, like for example, the part where the Moon King flicked the helmet off Kubo. If the grandfather's purpose was to protect the armor from mortals, and if he can touch the armor, THEN WHY DIDN'T HE JUST TAKE THE ARMOR AND GO BACK TO HEAVEN OR SOMETHING.
