I agree that the Dance Off is not working well. I really thought the purpose was to prevent another Cloris, but unless the judges use a different scoring standard for the Dance Off than they used on Monday then it doesn't give the judges any more clout than they had before.
I think it could be tweaked (as I suggested on another post) to let the Dance Off count for 1/3 of their total score, which would then give the judges 2/3 of the total score and the fans 1/3. The fans would still have 1/2 of the vote to determine who is in the bottom two, so their vote would still be important. This approach would send the Cloris (or Steve) types away a week or two sooner, keep the drama of the Dance Off, and overall be an improvement.
If they are going to keep the same rules, I'd just as soon return the old format of allowing the best couple to dance again.
