If I divorce my own personal feelings about Ariana from this, I have to admit that it is good:
Like, if Katy Perry or someone had shown up in this — not that I love Katy Perry, particularly, but you feel me — I am sure I would have given this an unmitigated praise hands emoji. So I have to give Ariana credit (and she apparently had a rough night, and was booed) and say…fine. Fine. Well done. You earned it.
