Well, I dunno. BTS at least has some substance. There is like a whole story line going on not visible at the first glance if you don't go deeper into their music and videos. There's even time travel involved. I think they are all around artists, it is not just about music.
Well the fans might be cringefest, but without them BTS would not be here today and neither would Hybe.
