The first publicity photographs from The Watch, a BBC America series "loosely inspired" by Terry Pratchett's Discworld novels, were released this morning and in just a few hours have prompted a massive backlash from fans of the series. Beloved characters and settings have been changed for no immediately discernible reason, resulting in a storm of protest from readers.
In an amusingly-timed move, Terry Pratchett's daughter (and respected video game writer) Rhianna Pratchett and his former assistant and partner in Narrativia Productions, Rob Wilkins, both tweeted a link to a 2004 interview with Ursula Le Guin, where she eviscerated the Sci-Fi Channel's appalling mini-series based on her Earthsea novels which changed the source material for no reason.
Unfortunately, with production drawing to a close on the eight-part series, it's far too late for BBC America to change course and produce a more faithful adaptation of the books. As a result, it's likely that fans will now have to wait even longer for a decent version to appear in the future.
