I won't judge her based on this performance really, she was fighting her costume throughout the whole thing and seemed too concerned about which camera to focus on to deliver any sort of good performance. I figure she must be a lot better doing it on stage where hopefully the costume is not her enemy, and she has people to play off to. I'm not a big fan of her talk-sing approach to the song (not as successful as Pat Carroll's somewhat similar approach was in the movie), but again, I'm sure it all comes together on stage in ways that they obviously didn't in this awkward performance.
