I get the distinct feeling that Parky is treading water - going through the motions in the twilight of his career. In his heyday (the 70s), some of his shows were classics. Those old, much repeated encounters with Billy Connolly, Muhammed Ali, even Rod Hull & Emu are still able to raise a laugh today because they were damn good entertainment. Now, although he still has some good guests, there seems to be a "waiting for the carriage clock" mentality about Parky himself.
As for Jonathan Ross, I'm in two minds about him. On the one hand, he's not so sycophantic to celebrity (than goodness). Any gushing comment about loving someone's work is usually a precursor to some barbed witticism or, in the case of a female celebrity, smutty innuendo - did you see how uncomfortable poor Nicole Kidman looked last night? On the other hand, I can't help thinking he's a bit long in the tooth for such schoolboy humour now, and I'm not keen on the wholesale "Lettermanisation" of British chat shows, of which Ross is a major culprit.
Oh, and if Shirley Ghostman is the future of British comedy, I think I'll stick with the past, thanks. The phrase "lead balloon" springs to mind.
