I have not seen Hogfather, but recall much, much squeeing from friends in the UK when it first aired. (I have seen the animated Discworld adaptations, which are quite cute: animation's a bit clunky, especially in comparison to the best modern anime, but the voice casting is excellent...Christopher Lee as Death is PURE WIN.)

I've heard a lot of complaints about the Antique drama changing Ono's backstory and making him straight, but haven't seen it myself yet. (I probably should read the actual series first, instead of just the author's smutty post-series doujinshi... *koff*)
