I kind of mostly agree with Drew's points, inflammatory as they are written, but also agree with Ves that its very much opinion and preference based
Clearly some people prefer the more kpop sound, the visual diversity and vocal diversity that groups like IVE, LSF etc offer.
Others obviously dig the more "signature" sound sameyness and visual closeness of groups like NJ,
As someone in the former, I hope the NJ formula isn't going to becoming the overarching theme for new groups going forward and into 5th gen. I just find that kind of... boring.
