The musical performances were great and worth watching the movie for. I think that the people outside of the main trio were much more interesting but they didn't get screen time. So yeah, it's lame. It's like the anime version of the movie Drum Line for jazz. (3/3)

Do prodigies like Dai exist? Yes. Yes they do, but even they have to face a lot to gain such a massive audience in the world of music because the music industry is so incredibly competitive. Dai never faces any challenges at all. He's just proven right.
