I agree with some of the above posts - definitely Darren and Emma. I think Darren's a wee bit wet and needs a warm, watchable woman (like Jill the Brill) by his side - Emma's a bit too "nativity play angel" cutesy. You can practically visualise her wearing a floaty white sheet and a tinsel halo.
But (deep breath) - and I think this is going to be controversial - one couple who lack chemistry and who should have it in spades is Carol and Matthew.
Don't get me wrong - away from the dancefloor I think Carol's attitude to the whole thing is spot on and I'd love to see her back doing more prime time presenting (pretty please d'you think she could oust Maternity Dress Tess?)
But on the dancefloor, for me, C+M don't gel. When he was caressing her "rear of the year" bumcheeks in the week 3 jive, he did so with the dispassionate disinterest of someone judging a pair of cantaloupes in a Women's Institute veg show for weight, texture and firmness.
Lest someone points it out, I know she's a married mum and, from what I understand, his interests lie away from girls but I don't think that has anything to do with it. In fact, I think they'd be great dancing with other people. I'd love to have seen Carol with Anton, for example.
But every week, they promise us sexy, steamy dancing and, sure, Carol kicks her (very fine) legs about a bit but there's no flashing eye contact, no playfulness, no intimacy - not that I can see, anyway.
I can really see what Arlene meant when she described them as antiseptic - on the floor they've got the chemistry and charisma of a Wet Wipe.
Speaking of which - if you could redistribute celebrities and their dancing partners (in this series and in previous ones) who would you put with who and why? (Please, someone, choose some decent partners for Anton)
