they’re very hardworking and their numbers are a great asset for performances. i’d love a butterfly remake, that choreo was kino and their scenic skills have improved a lot since
it’s a competition show with a handful of girl groups battling each other through performances (it has been adapted with bg too, see kingdom) to determine who’s the best basically. the first season had aoa, mamamoo, g idle, oh my girls and lovelyz, it was great and really helped g idle’s and omg’s popularity increase. each week the groups had to plan performances from scratch with original choreo, sets, concept using remix of their songs - some even did the producing -. the creative process was really interesting to watch and it’s a freedom that few ggs usually have.
there’s a second season coming but no groups have been announced yet, of course the groups that would benefit the most from it are mid range groups like loona so hopefully bbc has the funds to put them on.
