Actually lyrical jazz is not the dominate specialty - contemporary dancers usually make up the largest % of the top 20.
The show is on Fox - #'s are different in each market. In the NYC area, it's channel 5.
From what I read, they didn't like the ratings for the results show. So, Fox wouldn't air a results show - wasn't the decision of the producers.
I watched the dating shows one night and they weren't very interesting IMHO.
I think they've really made an effort to 'spread' the specialties of the competitors. This year we have 3 ballet, 3 latin ballroom, 3 hip hop, 2 jazz, 1 bellydancer and 8 contemporary dancers. Overall, though, the contemporary dancers seem to be the most adaptable and the hip hoppers have the advantage of having energetic routines.
I was surprised they chose Cyrus as the 3rd hip hop person. He was great at his specialty, but really weak (compared to the other 19) in the other genres. After prior issues with people who struggle outside of their specialties, I thought they would've gone with the guy who was good in the other genres, but had a so-so solo.
As for the ballroom girls, they are the youngest of this season's top 20. Between the 2, I prefer the one who doesn't do the over the top overt sexy moves .....
