I used to really like the show and laugh quite often. These days, everyone watches it, and when everybody watches a comedy show, it suddenly becomes less funny as the jokes don't have to be anything special to get a laugh now.
Frankie Boyle and Dara O'Brien are the only two worth watching for now. Hugh Denis is occasionally funny, Andy Parsons isn't really and Russell Howard is awful. He doesn't end a joke, ever, just keeps talking. David Mitchell and Michael McIntyre should replace Howard and Parsons, just to give the show a bit of freshness.
Like someone said, now, it's just 5 comedians shouting over each other trying to get unfunny bits of their stand up in. They should bring back Whose Line is it Anyway, the US version is brilliant.
I'd prefer 8 out of 10 cats if Jimmy Carr did one. Would I Lie To You is due on again soon so I'm looking forward to that, and the new series of QI!
