John Sergeant voluntarily withdrew after weeks of “null points” with the public voting him back in. His Paso was quite the spectacle, dragging Christina around like a sack of coal.
Kenny Dalgliesh was terrible, kept in by the sporting vote for weeks on end (didn’t his much better wife go out in an earlier round?). Ola Jordan spent so much time dancing around him in next to nothing that one of the judges (Craig?) described it as pole dancing.
Its not surprising that bad dancers with big fan bases stay in the early weeks and sometimes, particularly for sports stars that works and they get a lot better. Its annoying when they are totally rubbish, not improving and good couples go out in their place after the early weeks.
