Watched this last night. Started slowly for us, but loved it by the end. Good stuff.
Karl seems especially miserable this year
It seems as if Karl does not like Warwick at all, but might just be for the benefit of the camera. Karl would trade Warwick for a fat ginger cat in a second!
I think the Warwick addition is a good one, adding a new antagonist dimension to the show.
PS> At the end of the show, I did hear it airs Fridays at 9pm (UK).
