I love Terry Pratchett, but many of the TV adaptations have been a big miss. Though Good Omens was really well done, I thought.
“The Watch” is so far removed from the source material to the point where both Neil Gaiman and Rhianna Pratchett have denounced it as sharing no DNA with pTerry’s work (“Batman if he's now a news reporter in a yellow trenchcoat with a pet bat”), that I would be hesitant to even count it as an adaptation.
