I do agree that the concept of idol groups is problematic. I used to like a lot of AKB48's music but now I much prefer the 46 groups. Anyway, I don't approve of how rapidly sister groups are being formed. I'm not sure if it's still Aki-P making all the new groups or if it's AKS management, but it seems unnecessary to be expanding so fast.
Yea I agree, considering I read something about one of the sister groups just finally debuting a music video and some controversy around the original video being deleted.
