Maybe as a lazy watch this is fine.
The songs are beautiful, and I would suppose the movie has a proper meaning and message, and the art style is fitting for the story. Beautiful choice of colors!
The main character(s) of the story had a well put-together background and development and you could see a bond forming overtime in "U".
I would not say they reacted in a fully realistic way, but what happened in the movie could describe a little bit of how one would feel if now this was our reality. (Although, take it with a grain of salt.)
It is a light movie, so I would recommend it for anyone just wanting to have it on as a quick watch without having to follow way too much at once, and where it is light and hits you the last bits of the movie!
