First time I've chimed in on this thread, but I've been watching all season. I think the judges are too easy on Rob. His dances bore me. He has definitely improved a lot over the season and portions of both of his dances last night were very good, but other portions were a bore. I think his fluidity is awful. He's constantly pausing between moves. If they are going to deduct points for Rikki's lack of fluidity, they should be doing the same for Rob.
I thought JR's freestyle absolutely blew Rob's out of the water. It's too bad they had already given Rob all 10's, because there was no way to score JR any higher, and he deserved it on the freestyle. JR's timing was off on his cha cha, but he didn't deserved that 7. I gave all my votes to JR, because I think he is the best dancer, but I think Rob will win it, because it seems that's what ABC is pushing. All season, the judges have been so supportive and complimentary to him, which they should be to ALL contestants, but it's a sharp contrast to the way they treated some of the others. It's easy to gain confidence and improve when you're being constantly flattered while others are belittled for their efforts.
