The art was good at times, and bad at others. The animation would skyrocket during the piano scenes, as they would use CGI and stuff, but during the times when it isn't, it gets to pretty low quality.
The sound was great, one that really gives you goosebumps, one of my favorite openings in anime, plus the soundtrack that plays during their dialogues are top tier.
The characters were fairly good, there wasn't really anyone bad. They just weren't interesting, had obvious flaws, and at the end, some may overcome them while others don't.
The enjoyment of the show was outstanding, as good as any anime I have ever watched. The emotional ending and songs really make it one of the best.
Overall, 8 out of 10.
