She actually moves like this. She is incredible. It's like watching water... her transitions are wow. Love her, she's so refreshing. I think that this season's dancers are all technically very good... but not too many of them are exciting. By exciting I mean, they're just what they have to be, but not more. There isn't that extra sparkle of performance quality among most, that extra uniqueness in movement... I don't find them as interesting to watch in general as some of the earlier dancers, and by far not as much as season 4, where the dancers just had SO much more personality... hmm... we'll see I guess.

Anyhew, here's the clip!
