Yeah, you wouldn't tell someone in that situation, "I mean, have you seen Lupita Nyong'o? Cate Blanchett?" I see such superlatives as an expression of emotion and appreciation, something special shared in that moment between two people.

Incidentally I just asked my husband, a huge fan of Blanchett since we saw Carol, who was more beautiful, her or me, and he immediately chose me. I like it when they have a sense of self-preservation. XD
