There isn’t a lot to be said about this anime other than it is an underrated anime and you should really check it out if you enjoy music. Although, having knowledge of music is completely optional. The show gives you a real appreciation for classical music as it follows two children with vastly different backgrounds through their journey on becoming professional pianists.
With that said, its animation is pretty bad. Well, more like, really, really bad. The cut between 2d and 3d animation for the piano playing is jarring. Plus, any scene with a crowd is poorly animated, which is usually forgiven since these are one off occurrences in most amines. However, this show relies upon competing in front of a crowd, so the poorly animated crowds stand out like a sore thumb. This feels more like an anime that was produced in the early 2000’s and not a Netflix anime produced in 2018. The show is carried upon the music and plot alone.
