To be honest, I liked it. Would I watch it again? No, it's a movie to watch just once, remember it, whether in a bad or good way and leave it there, forgotten. The animation's art style, at least for me, is what kept me watching, even though I fell asleep around half the movie and had to watch it again from that part on, that's another thing, it feels really long, specially in some parts around the start and the end. Let's say it's an experience, and you should watch it when you had slept well and around 5 to 6 pm.
