Not really a fan of Shinkai's storytelling chops (I much prefer Mamoru Hosoda), although the guy does give some glorious beautiful animation. I've watched all of his feature length films (including "The Place Promised in Our Early Days" and "Children Who Chase Lost Voices" (his weakest, imo)---even his earliest work, the OVA "Voices from a Distant Star").
All his stories all feel the same, imo (except maybe "Children")--- overly sentimental love stories between a boy and a girl, a period of separation between our potential lovers, the girl being potentially lost forever to our boy protagonist, the boy running desperately to save the girl. It gets stale after some time. Perhaps that's why out of all his works, "5 Centimeters per Second" is still what I consider to be my favorite from him, if only because I don't consider it a movie that tries to tell a single story, but more a visual poetry consisting of vignettes, with more emphasis on the mood and tone of a moment than any sort of resolution.
That said, I consider "Your Name" to be the film where his storytelling skills have reached a level that's resonant to me, although I still found it a bit lacking personally. I still like it, mind, and I consider myself a 'fan' of Shinkai's animation in general. It's just that I have low expectations when it comes to his 'stories'. I honestly think "A Silent Voice" is better than "Your Name", but I'm aware I'm in the minority in this.
And I'm going to be bold and say that I find "Weathering With You" to be a better and more polished Shinkai film than "Your Name", because it makes better characterizations and utility of its side characters. It's also more coherent, and makes better plotting of events, although it's less emotional. But then I'm the kind of person who doesn't look for the 'emotion' in his films because I've been following this guy for years and has grown desensitized to most of his staples, so every time I watch his newer films I don't look for the drama but rather look for the ways in which he has improved.
So yeah, that's my condensed opinion on this movie. Back when this was more recently released, I would've written more but given that it's been years I have forgotten most of my thoughts on this film.
