I have a great deal of admiration for Bruce - a real trouper and an old-fashioned entertainer par excellence. He's a lot sharper than his fumbled autocue readings might indicate - he was very entertaining on ITT the week before the final when there was no autocue to slow him down, and there were flashes of his old wit when he managed to sneak in unscripted jokes ('lovely dress, Kara - I used to like blancmange that colour'). People who have been to the studio to see the shows being filmed are full of praise for him doing his own warm-ups (and doing them well).
But...
I, too, wish he would bow out now and let somebody else take over. The jokes are beyond lame; there is zero chemistry between him and Tess; and, basically, he adds little to the show. Having said that, the results show was the poorer without him, but only because it meant that Tess took over!
I take no notice of the BBC backing him now - they'd hardly say anything else, would they?
