Good watch, might watch again, and can recommend if you've seen any other version or are looking for a writing analysis.
During a lot of the movie, I was kind of in nostalgia mode, remember things I saw / felt when I was a kid, just sort of enjoying the way back machine experience.
It wasn't until almost the very last scene that it clicked how good the writing is in this. I know this is known for the excellent animation styling, the catchy tunes, and charming coming of age semantics, but this uses several strong formulas that have been used since Aesop's fables.
