I think Judy has struck the right level of self-awareness: "I know I'm rubbish but I'm enjoying it and trying to improve". She has revealed a sense of humour which was a pleasant surprise to me, having only seen glimpses of her looking dour at tennis matches (to the extent I have been inspired to start following her on Twitter) and she and Anton seem to have really hit it off. He seems to be enjoying it more than he has for years. Their ITT interviews are good fun and their VT on Saturday made me laugh, which is near-unprecedented. She does has appeared to have made slight improvement and has loosened up since the beginning of the series. Based on all that and the fact I thought she was better than Scott on Sat, I sent one free online vote her way for the first time.
Scott doesn't do it for me. I find his routines cringeworthy without any levity to balance it, he does across as paying lip service to enjoying it while hating every minute which makes me feel uncomfortable and sucks any possible enjoyment out of watching him, and I haven't yet warmed to Joanne, although that might be in part because she too is being forced down a "comedy" path and hasn't been given a chance to show what she can really do. I haven't seen any improvement in his dancing either.
In short, neither of them can dance but for reasons other than pure dance talent, I find Judy entertaining; Scott not.
