I tried to keep an open mind, but they changed a number of things that made it painful to watch.
4 changes in particular.
Here Angua the werewolf's backstory is that she was cast out for being a werewolf.
Meanwhile in the books, every single member of her rich and powerful family is one.
Carrot, while looking more like his book counterpart than anyone else here, is a teensy bit too short and wiry, but they keep in his adoptive Dwarvish parents.
The show having now firmly established Dwarves as a species, they introduce us to Cheery Littlebottom, the transgender Dwarf, who is taller and bulkier than Carrot. Just as Carrot is about to comment on the obvious discrepancy, Cheery says: "Dwarves come in all sizes". See, that doesn't just change things from the books, that doesn't work thematically, as it renders Carrot's struggle within Dwarf society utterly pointless.
And then there's Lady Sybil Ramkin, in the books she's a force of nature, built like a Wagnerian valkyrie. Always looking for the best in people and one of the few on a first-name basis with patrician Vetinari. Dedicated to the welfare of swamp- dragons.
In the show she's a wafer thin, cynical, vigilante.
It's at that point I realised that this "edgy" reimagening is less progressive than the 35 year old book it was based on.
Oh, and Death cracks jokes now.
