My introduction to Terry Pratchett was the wonderful Good Omens co-written by Neil Gaiman. I caught up with the first episode of the BBC/Amazon production a few days ago. Absolutely fantastic. I giggled throughout anticipating much loved jokes and those newly created by Neil Gaiman in his screenplay. Despite my reservations - I thought the roles should have been reversed - David Tennant and Micheal Sheen are perfect. Roll on the rest of the series.
