I must admit I've watched amazingly executed animated films but this one unfortunately doesn't make the list.
The story:
It had a lot of potential but even though the story was okay, it had a lot of twists and turns that could've been taken just a tad slower, but overall it wasn't terrible.
The p.o.v's:
In case you haven't watched it to me it felt like the perspectives were jumping from one character to another plus I think the movie experience would've been a little bit better if they added Nazuma's perspective, since it felt like her point of view in this was basically missing.
Character development:
Personally these characters felt pretty undeveloped if I could get at least some more insight on why the mc really liked the girl so much, and maybe a little more information on the little ball instead of it remaining a mystery
"Leave it to the imagination":
Throughout the beginning when trying to figure out how the ball ended up there, to the end trying to figure out why the two weren't in class. I've seen other movies do this before but for a movie that had such great potential had a bad time trying to do this in my personal experience.
Overall: 6/10
