Production value has shown the age of the CGI used but the props, themes conveyed, cast and faithfullness to the source material make it a real treat for Pratchett fans.
Despite the length there isn't enough time to fully introduce all the characters that span other books fully, so some characterisations/comments might fly under the radar but it is still a wholesome, funny & smart adaptation that (I feel) retains the feel of the novel that I have read time and again.
