I really loved this one,it's quit sweet. Sure it remindded me a bit of a live action film, who's name I forgot but it also is about a son taking mom to the mountain where old people go to die so probably the movie took inspiration from this anime. But as it's the problem with old animes this one also missed sound or at least music that would make it even more perfect. The animation also despite being quit beautiful at times it was a bit jankey or rather twitchy so did a bit run the enjoyment seeing the characters jerk and rwitch, but wasnot like a fully ruining the anime, yet still not a 10 out of 10. Despite the flaws I mentioned this one is still a hidden gem.
