Not to sound Karen but honestly as someone who used to love kpop MVs nowadays i mostly watch performances instead. A lot of these groups are going for such high budget MVs which i think i am supposed to like it for that reason (?) but they are usually too fast paced in some scenes and they seem to lack the color and vibrancy of previous kpop MVs. I also dislike it when they edit as if its been filmed on phone or low quality camera as an aesthetic. They all go for this very realistic vibe which I guess is some kind of trend New Jeans set. I really like ILLIT but even their MVs lack the lovely colors and fun vibes you get from their stages.
Anyway, if i choose one i guess New Jeans' bubblegum.
