Story:
It's not bad. It has a nice concept behind it with them trying to throw in a nice plot twist that's foreshadowed earlier in the movie but it's also predictable because of that. The plot twist could also have easily been replaced with something else in the movie, something that is introduced early on and is an existential threat. The plot twist makes one of the main plot points of the movie, the pancreas of the girl, completely ignorable. The main reason for this is the blank slate characters to whom we feel no sympathy or emotional attachment. But, the pacing of the movie is astonishingly good, better than many other movies, and especially most of the Ghibli films I have seen so far.

Animation/Art:
It's beautiful. It looks very good. But there aren't too many scenes if any that would cause animators a big challenge. Also, their crying animation freaking SUCKS.

Sound:
meh. Forgettable but certainly not bad. nothing special, nothing terrible, average I guess. passable. LITERALLY, ANYTHING TO SAY meh

Characters:
BOOOOOOOOOOO!!! They are not good. The guy is the most bland, emotionless, blank slate boring character I have ever set my eyes on. Like those shows where the character is a blank slate so the audience can put themselves in the character's spot except in a movie. The thing problem here is that shows often use it to evolve the character from scratch or have side characters enough to keep the audience entertained. This movie has neither. Because of this, evolutions in his character often feel sudden and without any good reason. The girl is irrational and an absolute jerk. She teases him in a way that could be assault, is fine with taking assault, and does nothing to earn any sympathy. She's like a blank slate but happy all the time. I am completely uninterested in either of them honestly. I can't even talk much about them besides that. They just suck. I've never rated something this low before.

Acting(subbed):
meh. The exact average. I was completely unimpressed by their performance. But I wasn't dissapointed by their performance so I guess you can say that at least... I really can't say they were good but they weren't bad sooooo

Enjoyment and Overall:
I really don't understand why people liked this so much. While the pacing was good the story itself was so bland and boring that I nearly fell asleep. This movie is just not good. A movie should at least be enjoyable and yet somehow this movie had no hint of joy sparkling in me. So much of it was average and plenty of it was bad. I really just can't see why people liked this. I'm happy most of the people who watched this did. But I just fundamentally disagree on the quality of this movie. I am an active hater of this movie. This becomes more and more clear the more anime I watch.
