I liked it and thought it was a shame they didn't have enough time to allow the music to reach its crescendo. I did recognise some AS in there, though, obviously it was high concept and will inevitably loose some of the feel. I actually liked the dance infinitely better than I liked the silly film.
As for the way she performed it, it was respectable. She is obviously no ballerina, and there were some minor hesitant moments, but I thought she did extremely well.
I'm waiting for it to pop up on YouTube to watch it again, along with Alex's dance. Both were stand out dances for me tonight.
