The story really hits you in the gut, you'll like it, especially if you're into movies like A Silent Voice. It's not like other romances I've seen, this one takes a different approach to adolescence that I haven't seen before.
It was a shame the subs I used didn't fully represent the story. It wasn't just that the english wasn't great, but many times they completely mistranslated what was said, or left out details that would've added so much more depth and understanding. Also they didn't bother translating the songs, which are pretty good.
Art:
The animation's pretty high quality. There were some moments with slightly bad CGI (since the film was in development hell for a while), but it never detracted from the experience, and tbh I didn't notice it much. The rest of the visuals were great, with a lot of wallpaper worthy scenes. If you're familiar with the style of Your Name or Weathering With You, this film's style is similar.
Sound:
SFX wise it's pretty standard, nothing that pops out. The music is amazing though, it fits the tone. The subs I used didn't translate them, which is a shame since the lyrics perfectly matched what was going on.
Character:
The characters are what drive this story. They're relatable and memorable; this story really puts you into their perspective. They're also written realistically, with realistic motivations. I never once thought of any of them as a character trope.
Overall:
I thought it was a pretty good, you should at least give it a try. Although maybe after better subs come out, as of the time of writing there only seems to be one group that subbed it.
