Just how it came across to me, but I really felt that when Dave looked fed up at the comments, he was doing that because he thought that was part of the panto nature of that part of the show. Like the crowd booing. I don't think the celebs are meant to act like they couldn't care what the judges say. By the time he got to Tess, he never seemed bothered by the comments, and if he was genuinely upset it would still be obvious then.
Yes, he is proud of his standing ovation, and I'd guess that Ben and Natalie have had bigger this year, let alone Louis's foot-stamping last year, which I think was the loudest I can remember. But let him be proud of his standing ovation it isn't taking anything from anyone. As long as he isn't saying he's the People's Champion, I don't mind.
I don't think the people who are less good at dancing should be constantly apologising for their existence. I don't want to watch that. Dave should be very proud of his time on the show. He's a nice man and he did his best.
