I never said they were bad, they had their fair share of very good moments objectively, but you are too influenced by nostalgia. I totally understand that all 2ne1 fans were over the moon to see their comeback, and the tour that's coming soon. But objectively the performance they did today wasn't good (their coachella performance was far better).
And sorry to say that they are not the best girl group on stage, they were very good in their prime, one of the best girl groups objectively in kpop history but the best? No, and I will not participate in this lying story telling.
I know but that doesn't change the fact that they have surpassed their model. At least this one, cause i'll not say Hwasa surpassed Beyonce.
