The dullness and sheer shrewish repulsiveness of the book is faithfully brought to the screen. So faithfully I was only able to endure the first episode before turning it off. Harriet Vane isn't as odious as those with whom she associates--but what a clutch of harpies.
Now, I know that this was Sayer's version of A Room of One's Own arguing for the possible academic integrity of women studying at a university. But it is an unfortunate venue populated with the Oscar Wilde version of a fox-hunt--"The unspeakable chasing the inedible."
In case you haven't noticed, I'm not a fan of Gaudy Night as Tom noted, I constitute a very small (but vocal) minority of Sayers' fans. On the other hand, I am truly a Sayers' fan and only reluctantly a partisan of Lord Peter Wimsey, who I generally find as apalling as the characters in an Evelyn Waugh novel. (Can't wait to read Black Mischief.)
