Well, that is true in a way, but if there is underrated, then there should be overrated right? Because I can think of many groups who are underrated.
I do think too that some groups deserve more attention but it’s not because I have this opinion that everyone will have it. Same for the overrated groups, I don’t see anything in a lot of top groups but theirs fans do.
Not so long ago I saw a fight between Kpop fans of two different fandoms because one fandom was stating that Kpop was only for fun and that the lyrics don’t count whereas the other fandom said that they care a lot about that. ( easy to guess what fandoms I am talking about).
There are people who are visual stans, some others who are personality stans, some people wil more focuse on discography, some others on vocals, on rap, on dance and some others on performance so they expect a good stage presence from the groups that they stan.
Personally I don’t care a lot about dancing, visual and stage presence. I am all about rap, vocals and discography and I am a personality stan. But my brother is mainly into Kpop for the dance and the performances and so when we speak about which group deserve more attention according to us, we are always disagreeing.
Just to say that all of this is subjective.
