I think I have no words to describe how great is this show. I became interested in it because it had been a success in Japan, but since it's a very long drama I hadn't intention of finish it. But once you start you just can't stop. All the characters are memorable, and the acting of all cast is incredible. It's been a long time since I laughed so much. There are sad and frustrating moments too, but that's why the history isn't repetitive or boring. Also, you don't know what will happen, it's interesting until the last episode. The soundtrack is brilliant. They sing too many times the same songs but at least there are good songs. The opening song is very good too. If you are interested in ama or j-idol culture you must watch this series. If you're not interested in them I think you should at least give a try because it's fantastic.
