I hardly think when Matt was "assigned" to Lilia they expected him to get this far in the competition, so that is a non=starter really. Darren, height=wise could only have been paired with Emma or Louisa, as could Vincent, so it is that which decided who he danced with.
Tonights show was dedicated to Emma and Darren, just like last night was Mark and Karen. Tomorrow night will be devoted to Matt and Lilia, so I fail to see the problem. And, personally, I thought it was good to see one of the professionals, arguably the best choreographer there, get the credit they deserve for their routines. Also good to see the other professionals crediting one of their own with great choreography and they should know.
It does seem as if some forum members would complain about 2 seconds of Emma in the week as overkill, which is a little ironic, as those who are the most vocal about BBC bias seem to be the most biased themselves.
It is interesting that many of the top professionals are supporting Emma as the best all round dancer, again they should know, and despite all the vitriol on here at times about the paso doble it was interesting to hear James say how good it was, and Erin say that it deserved a 10! I think that must prove something, unless you believe all the professionals are part of a conspiracy too, and that they, along with the judges, don't know what they are talking about.
