Sorry to be a bucket of cold water, but - while I might watch it since I do watch an appalling amount of TV - the idea doesn't appeal to me. I think it is a prejudice that they'd all be would-be celebs just wanting to be on TV.
What would they be winning? With X-Factor/Fame Academy type shows (and I loved FA) or The Apprentice, Restaurant, etc etc, you're watching (in theory) people with talent who need a break, and it's only worth it if they have got a reasonable chance of making it afterwards (imo). With SCD you're watching people having a go at a new skill for fun, who then return to their real jobs - and are not intended to be dancers afterwards. If there was a programme where non-famous people learnt to dance with the pros, just for the fun, and won a glitterball, would they just be supposed to go back to their lives or become dancers/TV personalities? Because, from what I can see, once people have been on TV for weeks and weeks (and I'm not judging them for this, I have no idea what it's like or how addictive it might be) many, many of them seem to struggle to go back to their previous lives, they carry on wanting to be in the papers, and I find this quite sad.
I would love it if SCD ran a competition where people could win classes with Brendan, Anton et all - I can completely see why people would want to do this themselves. I would just rather it not be on TV. Sorry if that makes me a killjoy.
