This is mostly for fans of Bishounen and naturally JPop.
I liked the songs the best and the eyecandy second best. The story was nice all-over but too often very kitschy. What I liked least was the CGI used in the OP/ED and generally in the concerts... Also I was often kinda annoyed by the English-speaking.
Other than that it was enjoyable to watch and it had a somewhat open ending so more might come?
