A moment that sticks with me is the woman on the stairs who starts cutting herself, very effectively staged.
Anyone have anything to say about the one who spiked the punch? At first, I just shrugged because it didn't really matter or add anything, but as I thought back she was an instigator. I can't put it to words yet, but I think there's a connection between it being her and the way she's used in the dance scene. You don't notice her among the group until it's her moment and then she peels off a dress to reveal a really small bikini, so that even for a dancer her frame seems large and her body less toned. She then struts away from the group like a runway model, leaving them behind before breaking into her solo. It's kind of an antagonistically showboat move. Contrast that with the star, Sofia Boutella, whose solo is surrounded by the rest of the group moving with her, or the B-Boy who becomes a human puppet, manipulated by the other dancers.
