I really like the movie and the story entertained me. I especially like the dark theme of death and loss. My main negative point is: They travel to Agartha after 40 minutes! The introduction takes too long, they should have spent more time in Agartha. Unfortunately this leads to some themes not being explored or explained enough. But apart from that, it's a great movie. Agartha is a very interesting world. The artstyle is amazing, as always in Shinkai's movies! You could just pause at a random scene, print the screenshot and use it and hang it on your wall like a piece of art.
