This is a really sweet film. This anime has one of the most vibrant color palettes I have ever seen on screen and its animation clearly was worked on with a lot of hard work. To top it, the plot is really sappy and kind of melodramatic, but I don't think this necessarily hurts the film. People who love slice-of-life/romantic animes will get a kick out of this film, but I can't promise others that they will appreciate it as much since the third act does drag on and the use of music is a bit excessive creating a feeling of disingenuous drama.
For me, I did tear up a bit. The hand-painted cells are just amazing and I can be a sucker for sappy romance. And the plot does give something to the audience member to engage on. If I was more tolerable of the "Anime Music Video" vibes I was getting from this film, I might have rated it higher. I implore everyone to give this film a try and hopefully you'll get more out of this film than I did.
