I think you're both going to extremes tbh. The reality is somewhere in the middle.
It's true he doesn't have to completely ditch what he's done before, but on the other hand the format of the wipe shows *is* getting rather stale.
Plus, I'm not convinced he's actually that funny - so I find his attempts at humour tiresome. He's much better when he's making serious comments about things I think.
Perhaps that's the answer - he should try something a bit more serious? I don't know. But one way or another, the wipe shows that were must-see TV back in the day I rarely watch these days. If I do watch them, it's only if I have time to get round to it.
Try the Daily Show with Jon Stewart on Comedy Central Extra that is a bit more serious.
