It's tough to give a reason other than "vibes," but it made me feel a broad range of emotions throughout the film, had beautiful scenery/animation, and had fun and quirky characters. Plus, this one felt much more "adult" than most Ghibli movies, which surprised me in a good way.

People are saying the plot is jank, but I've never gone into a Ghibli movie for the plot. It's more of an emotional experience to me.
