I bought Hogfather because I Iove Terry Pratchett's work. I am not normally a reader of either fantasy or science fiction, but what Pratchett writes is brilliant and very funny satire about our world, disguised as the imaginary Discworld. If Hogfather and Pratchett's other works are "mere fantasy" so is Gulliver's Travels. Where Swift and Pratchett differ, however, is in Pratchett's huge generosity of spirit and affection for his characters. Where Swift points out our human flaws with "savage indignation", Pratchett does it through laughter. Susan and Death are among my favourite characters.
The video is brilliantly done, faithful to the work, superbly acted by a cast of some of Britain's best performers, and with very high production values. I would say exactly the same of the other video I purchased, The Colour of Magic. I watched a friend's video of Going Postal. Same thing. I haven't seen any of the animated versions. Not sure I want to.
