i didn't watch the episode i just watched the performance and i must amit that i expected something better from this unit considering the members they had but the reason why i didn't enjoy this performance as much than the other ones, even the unit who didn't do really well or did a lot of mistake in the performance, is because to me they didn't really understand the vibe of the song their facial expression and image on stage were too strong, they try to hard to give a badass expression on stage and it's not exactly the "vibe " of this song, the song is more flirty , seductive for example Exo perform this song perfectly because they don't act tough or like the baddest on stage they are more trying to seduce the viewer, and the choregraphy also show this more flirty , seductive image of the sound and sadly i didn't feel this in their performance, i felt like their was some kind of gap between their expression and the music and that's why i couldn't really enjoy their performance meanwhile i felt that even the groups who didn't do well or did some mistake at least try to exude the same energy than the song portray
