Have you ever feel that sensation when a music deeply touch you? Well, this movie's a representation of that. A simple yet stylish one at that.
I know some people would be put off by how simple the art is, but don't be fooled. Because they have more trick up it's sleeve that will blow your mind. Especially when the music affect the characters deeply, the style change into and become more vibrant, expressive, almost experimental.
Also, even though the plot throughout the whole movie is not impressive and the dialogue is banal. There is still something about it. Probably that help with how the movie show contrast between living ordinary life and doing something you love, something that you cherish a lot. In this movie's case it's music.
This one's felt very raw but fun. Definitely a nice watch if you're familiar with Japanese movie. It has that slow paced japanese movie feel to it.
