Definitely worked bette with the extra 20 minutes. I don't get the comparison with Charlie Brooker though - the guests on Weekly Wipe are nothing more than one of the many features within it, not the central premise of the show.
No, but that wasn't my point. If you're going to go to the bother of hiring a studio and getting in a couple of guests, why only feature them for 5 minutes? It could be extended, like The Last Leg has been, without having to rush stuff.
