Yeah, I'm holding on watching Majisuka 3 for now. I loved the first two seasons. But I don't particularly care for the younger and/or newer members that much. I don't know if this is just something I've made up in my head since I don't know much about Idols, but it seems to me that AKB isn't much like the Morning Musume type idols (which I can't stand). It seems like they are a more unorhodox group in different ways. They seem more raw and honest while Morning Musume feels too innocent like and pretty fake in their personas. Again, I don't know if it is true, I know far to little about MM to say that this is the case, but it is how they have come off on me.
I like AKB for their different persona types. Like we have Sae who is very boyish, Akimoto (Sayaka) too but in a different way. We have Yuko who is very energetic and funny, Mayu is very diva-ish and "innocent" like and so on, and so on.
Anyways, what I was getting at with this way to long build up was, the younger members of AKB seem to be more of the generic idol girls to me. I've seen them sometimes appear on like AKBingo and their personalities seem really flat.
