I'm happy that they finally animated the entire story, if you can call this animation. If you like classical piano this is worth watching for that alone. They got some of the best young pianists from around the world to stand in for each of the different performers and they did incredible jobs. The best part of this is the performances.
They show motion by overlaying some moving bubble layer on top of the audience and pianist whenever music is being played, and by panning over still pictures. All the CGI from the first season is gone and everything has been replaced with stills for the most part.
They left a lot of the story out because they only had 24 episodes total, and while that included some of my favorite parts the heart of the story is all present. This is based on second half of one of the greatest manga ever written.
