The opening sequence featuring clips of the semifinalists is trying to be all tense and dramatic and uber-competitive. Then the show starts and the troupe and pros are doing a goofy jive with a bowling theme. Tonal whiplash.
The opening credits tell us that 10 years ago a tradition began, and we see brief clips of some of the past winners. Then we're told tonight a new dance era begins, before this year's "stars" are introduced. This year more than ever it's hard to defend the show's definition of "star." I have no idea who half these people are.
