People didn´t like this because it was too cliched and too overdramatic. Well, I liked it because it was a music-oriented anime after all. Artists need to be sentimental and eccentric to feel inspired for their music, they aren´t ordinary people in the first place. What I didn´t like that much is that they overused the flashbacks even in the middle of a concert! I get why though, they only had like 12 episodes to show and had to include every possible content until the end. There´s still the manga ongoing so it´s a nice intro to a decent shoujo that can be liked bymany.
