I just watched this now. When I watched Mariah and Carlos dance the jive my first thought is that they were going to get nailed by the judges. It was way too fast (choregraphers fault) and they could barely keep up. It looked sloppy and rushed to me. I was right. Had they gone later, their critique very well might have been worse! What followed were spectacular dances.
I don't find Mariah compelling; her smile face is not genuine or does not appear to be so and her hair is too brassy. Ok, that the physical but it is part of the package. Not sure about her personality yet. I didnt see them geling as partners.
I am not fond of the blonde with very short hair either and I am not sure why. It is still early and I may change my mind, of course.
I don't know names yet but I do remember Fiction. Wow, what a nifty young man and he can dance! I like his partner, too. They are a solid team.
