These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ensemble Darkhorse: The Death of Rats, both to fans and to Pratchett himself (he says he has no idea where the character came from, but he liked him too much for him to be lost with the other Deaths at the end of the book).
Macekre: Inverted. According to Word of God, someone once claimed to him that the book was somehow actually better in the German translation. Any German speakers who have read both versions, elaboration would be welcome!
