With a wholesome story and beautiful visuals, it's great to watch. The parts, in the beginning, are hard to follow, but reaching the end makes things more clearer.
If you wanna watch it, go in with an open mind, try not to figure out everything, the movie will make sure that you are satisfied with the ending. The overall mood of the movie is jolly and there are not a ton of emotional moments.
Hiroyasu Ishida has got some great sense of 3 point perspective drawings, which turned me into an instant fan. Its aesthetics are great and the animation is beautiful.
