If they are going to bring in guest judges why not someone who can act, sing and dance eg Angela Lansbury, Elaine Paige, Liza Minelli etc?

I'm so pissed off at Strictly for doing this. They don't need X Factor style stunts like guest judges; just stick to the winning formula. And how dare he give out the first 10 of the series?!!! Grrr!

Well I guess the answer to the thread title is -

unlisted option 3) A bit of a knob

Whose ever idea it was to have him as a guest judge should be taken out the back - and shot. Totally unnecessary and awarded some really stupid marks. Don't care if it was for one night only or even one minute.

I thought Donny spoiled the show tonight a little bit and added nothing. His comments were cringey and scoring all over the place...
