A little later than usual, Caleb and Sarah continue our run of Series 5 commentaries.
Comedy masterpiece or a joke too far? We take a long hard look at Gareth Roberts’ light-hearted fish-out-of-water tale and ask some serious questions.

Let us know what you think, in the comments below or via Facebook and Twitter!
