Sorry to join in a day too late, but I just watched this last night.
I agree that it was all a bit low-key in tone, but after all these over-the-top silly sketch shows that are doing the rounds it was a breath of fresh air. I love The Peter Serafinowicz Show, but it was nice to see a show that didn't depend too heavily on impersonating celebrities or, to be fair, dressing up that much (besides the judges and Henry VIII obviously). What struck me most is that this was obviously written by a small, core writing team or performers, as oppose to the generic, mass-written sketch shows that are popular at the moment (Rush Hour, The Wrong Door, etc.). This gave the whole thing an real identity that a lot of sketch shows sorely lack.
The Richard Madeley song was the highlight for me - we'd seen the same guy on a BBC Four show about comedy songs and thought he was amazing.
However, I didn't get the poem about the guy at the checkout either. Is this the same guy who was doing poems at the end of Charlie Brooker? I didn't find them funny either.
