It's a show about dancing, so the judges are right to comment on how shite his dancing is. It's a shame he feels he has to leave, but he signed up for the show in the full knowledge he would be critisied for being rubbish. It's not suprising that a half-witted proportion of the great British public can't even enter into the spirit of the thing and vote for the dances.

If it's simply a popularity contest then you might as well watch Big Brother.
