BGs need to not cover GGs if they are gonna be aggro about it

Hmm I never invested that much effort about gender in choreo covers. A lot of groups put their own spin on choreo, regardless of gender, usually related to their dance style.

I just look for is it a great cover?

NCT choreo is hard and people who cover it never seem to nail the combination of technique and attitude but I love this Billlie cover, which does. They’ve made tweaks to a few points in the choreo but I’m not bothered by it (notably eliminating Taeyong’s dramatic intro hip thrust, which itself varied by venue, becoming much milder on music shows and award shows, and the NCT hand sign and finger guns.)

Or I also look is it a dancer I like? I love Seulgi as a dancer but she’s not usually given much to do in RV so I enjoy her covers of more complex choreo.

all boy goups do is cringe and boring so why the surprise?

I don't see the problem. If a group does a cover to something, aren't you suppose to put your own spin on it?
