Congrats to everyone involved with Frozen - for breaking the $1b threshold and winning at the Oscars. Nice!
As for the performance, I didn't particularly care for the arrangement. I suppose it could have just been me, but it seemed too rushed, too fast-paced. I understand the constraints of television, of course, and the need to both cut out sections of the song and ramp up its pace. But it didn't give Idina Menzel enough chance to really let her voice soar. She still handled it exceptionally well, I thought.
