I get really frustrated when the same few "stars" get wheeled out again and again to the point where you just become sick of the sight of them even if you quite liked them originally.
It happened with Tony Slattery many years ago (not a happy ending) and also Caròl Vorderman.
Nowadays I can't seem to go a day without seeing Romesh Ranganathan, Tom Allen, Dr Michael fucking Moseley and even, God love her, Olivia Coleman.
Who else is over exposed? I'd love to see some more actors and presenters getting a share of the work but producers/casting directors just seem so unimaginative.
