I was quite surprised that this movie has very deep religious and spiritual elements. Actually, if the audience has sufficient religious and spiritual knowledge beforehand, then they will definitely understand the core story and the premise that this movie wants to convey. What I like about this movie is, it is able to build the atmosphere and emotions of the audience slowly. This movie will not let the audience get lost in boredom for long. The quality of the animation is also quite detailed so that the audience feels amazed and terrified at the same time.
