Replace Carrie Ann, and stop her lift rule that seems to be her baby and not an issue for the other judges.
Replace Brook with a dance pro. Perhaps rotate this position with the most recently eliminated pro for the interview segment and let Tom do the hosting alone. No need for him to split this job; he can carry it easily.
Keep Bruno. I like him but a little direction to tone down a bit is needed.
Have dance pros demonstrate the dances that are to be judged and give a brief commentary on what they are looking for so when we watch we can focus on the foot work and postures that create a high score. It would be fun to guess what the judges are going to critique, as we watch them dance.
I don't think they are deluged with "stars" wanting to be on this show so I am resigned to some questionable choices. That is fine with me. I have no problem with using the word star in the title. This horse has been beaten to death. It is just verbal short hand for recognizable faces in the media. Let that go.
The results show could be 30 minutes.
