Probably the first time Pratchett found a really rich premise for the Discworld. His witches are an improvement over the trio in The Black Cauldron (1985), a similar compromise between stereotype and character.
Oddly faithful. It preserves even the most literary jokes, which doesn’t make sense for a film, and it animates the silent movie gags instead of using film. It’s also too cheaply produced to bring any visual pleasure to the adaptation, and it adds a few stereotypes (like the enhanced appearance of WxrtHltl-jwl, pronounced here) but its overall faithfulness is sort of endearing.
