here's my Natalie ramblings...
The dance that got her cut was her style, she should have killed it.
She was great when dancing with Brandon, not so great with a boy who wasn't so great.
Doing it right in rehearsal means nothing. ratings, ratings ratings
This show (which luckily calls for a "favorite" dancer, not the "best" dancer) is also about learning choreography fast, stamina, consistency and personality (remember Sabra)
And of course, judging dance is subjective. Look at all the disagreement on Brandon ( they are pulling the same crap with him that they did with Danny)
