I really don't understand the other references about this movie, in my opinion it didn't seem like a bad story, in some way it was a fun and interesting story to spend the time. I really liked the design of the characters, the scenery, the animation and especially the music. I didn't know that this movie was made to promote a band, however I think it wasn't bad, they knew how to develop a simple, unfunny, but not boring story, so that's why my score isn't so low. Don't expect to see character development in a one hour promotional story, it's a simple and goofystory and it's okay to watch if you have nothing to do and want to listen to good music.
