I've now got to the point where I don't actually care who wins - for the first time ever.
What I would love to see, however, is Chris in the final so that he gets to do a show dance. I fully accept that Ricky and Ali are better technically, but he is the one I get the most enjoyment out of watching (and I say this as someone who has previously supported the best dancers and even been inspired to take it up myself).
So the best thing from my perspective would be a three-couple final where they all get to do everything, and then I really don't mind who wins.
