Somebody who can;t write anything for themself shoehorning zombies (oh wow a pop cuture thing! Why not stick ninjas and pirates in too?) into Austen. He even admits most of it IS Austen.
Well, that is sort of the point of parody.
No, parody would be if he rewrote the story. Taking the story and leaving most of it as is and sticking a couple of paragraphs in here and there is akin to wiping his bum with the pages. But it’s not parody.
Example: Spike Milligan’s Frankenstein. A bloody hilarious parody. It’s the perfect example of parody. The Frankenstein story is rewritten in Milligan’s piss-yourself-laughing style. With the exception of the general plot of Frankenstein, it’s entirely Milligan’s work (I believe he did Black Beauty and Robin Hood too but I’ve never actually seen a copy).
