As I long-confirmed Wodehouse fan, it pains me to say this but actually, no it wasn't very good. Better then bloody Downton of course, but anything is better than Downton. At least we didn't hear "learning curve" in Blandings.
I am a huge admirer of Timothy Spall but he is hopelessly mis-cast. Such a pity as we don't see him as much as we should on TV these days. His Barry the Radish in Auf Wiedersehen Pet was just wonderful.
Same goes for Mark Williams as the Butler...just not funny enough I'm afraid.
Jennifer Saunders is much more promising though.
Still, after one episode its difficult to tell....maybe it will improve ?
