I have to say so far out of all three weeks, Alex has done the best IMHO. I know a lot of people questioned his Broadway Fosse last week, but to me it was a bit reminiscent of dances in the "Pippin" video done back in the 1980s - including the leaps. There was one song - "The Right Track" - where Ben Vereen and William Katt did a split leap jump - and a few other more balletic dances. Vereen also had some similar steps in a few other songs in that musical.
Doesn't mean that it was the best by any means, but the whole "It's not Fosse" vibe I had read somewhere else wasn't quite accurate.
As far as this week - absolutely stunning, and he did take the critique to heart from last week IMHO.
The other dances didn't really super wow me, though I did like Ade's of this season's hip hop and I think Ashley's contemporary.
Melinda probably will leave this week - her taping did not feel like it fit the music (last week's was better) and the salsa was arguably the weakest.
I also agree with the assessment of Robert, but Billy is the other one I'd like to see in the bottom three. He's got this "entitlement" feel to me but he's not backing it up. While I do feel Alex at times may have that vibe, he can at least back it up with his dancing.
Kent is Kent - even if he doesn't win I think he could do well in Dancing or even acting. He's got a great simple charm about him that makes him work.
Lauren's was OK to me, but I bet she'll make sure her outfit is where it can't "malfunction" as easy. That possibly affected the dance depending on when it occurred.
