Ok so I was finally able to watch the performance, and while it obviously wasn't great, it also wasn't NEARLY as bad as some of you made it out to be

The only serious vocal issues were Ally's part (I don't know what happened to her today, her live vocals usually slay) and that Dinah's part was a bit too soft for some reason. I thought the other 3 did pretty well (not amazingly, but not horribly either) - in fact, Camila's runs in the last chorus were tighter than a lot of other live runs she's done in the past.
