But all eyes may have been on the judges panel which included, of all people, Carmen Electra in a sheer, low-cut ensemble. I could see Debbie Reynolds last week; at least she was a tap dancer in her day.
But Carmen Electra? What can she tell contestants about their dancing?
It turns out, not much, despite the long list of dance credentials she spouted at the start of the show. Her comments were filled with mindless generalities and sometimes she just repeated the comments of the other judges.
Those other judges included former contestant and now acclaimed choreographer Travis Wall, whose comments were pointed and who almost always had helpful tips for the dancers. (And he also was wearing a very dapper purple velvet jacket.)
Mary Murphy and show creator and producer Nigel Lythgoe completed the panel. Among the new choreographers were Justine Giles, Ray Leeper, and Chucky Klapow.
While the dancing by the pairs showed various degrees of proficiency, it was the group works that stole the show. Wednesday's episode started with a Justin Giles piece for the men about the stages of grief during a breakup, with each of the seven male dancers taking one of the stages. It was especially powerful when all seven moved close together, each locked in the steps of his own stage.
The show's ending - a strong, jazzy Ray Leeper-choreographed piece for the women about a group of James Bond-like operatives out to rid the world of men - brought audience and judges to their feet.
