Maybe the judges are actually judging the dancing?
Yes I know that's their job but let's be honest, the best dancer rarely ever wins. Why keep people the public aren't bothered about for weeks and weeks, especially as Montell has 0 chance of winning it. Surely it's better to keep people the public want to see.
The judges have too much power and it should be like the old days when the couple that came bottom of the combined judges and public vote is eliminated. With the dance off it means unpopular but technically good people are kept week after week and it gets boring and predictable.
