Same here, I thought the fusion was going to be gimmicky and forced but it was really well done and some fabulous routines.
I also agree that Louis has a presence that Dani lacks. Kimberley varies a bit too, in the same way as Louis, some weeks she makes much more of an impression on me than others.
Same with Lisa and Nicky, he may be technically better but he just doesn't hold my attention as he dances, there's no wow. Whereas Lisa is full on and makes you sit up and watch.
