I'm more worried for Kym after watching that: they did her dirty with the song choice. There's a section of "Only girl in the world" that would suit a bit of very staccato, very precise cape-work though. So hopefully they'll attempt and nail that. Costumes go a long way towards selling a Paso too. Fingers crossed.
I kind of think the opposite: with the exception of Mardy they are all a really nice bunch, great dynamic, good standard etc so it'd be nice to see virtually any of them in the final.
I see what you mean though in the sense that I haven't had a nailed-on favourite this year: I think the only person I've voted for every week is Hamza but it wouldn't upset me to see him beaten by Kym, Fleur or Molly. Well, maybe a bit if it was Molly
