The pacing during the first... roughly 90% of this movie is good. The relationship between Wataru and Sophia is given nearly no development, which gives a scene towards the end no impact and a feeling of randomness. The ending, overall, would have had more impact if it wasn't done so abruptly and delivered in such a bland way. A 6/10 is all I can give this because of its rushed feeling ending. Again, it is a great premise. It just fails to deliver a satisfying story due to poor relationship development and a lackluster ending that doesn't stick the landing.
