Not that it's worth anything, but here's my opinion ...
I have no problem with Denise being in the show - fine, she has danced on the stage, but she hasn't learned ballroom or latin dancing, so it is all new for her too.
I think the fact that she has danced on the stage before is detrimental to her performances - they are technically correct, but to me, quite cold.
I hate people comparing the dancers, but I'm going to, in order to make a point.
Lisa is not technically perfect by any means, but her total enjoyment makes her far more entertaining to watch. She interacts with the audience much more, whereas to me, Denise is going through the steps (brilliantly, but with no passion)
Michael is also not technically perfect, but his improvement is just fantastic to watch. I really didn't think he could top the last two weeks, and for me, tonight he has.
I would much rather watch enjoyment and progress, than someone going through the motions.
