I have seen Hogfather, COM and Going Postal.. liked them but I watched them as what they were.... referencing DW. Thought Going Postal was better than the other two. But I thought Hogfather was darker than GP.... which was an aspect I liked. See I love Death and I think the only way I would see him the same way I see him is full CGI.
I don't think anyone could ever satisfy a DW fan on every single character. You only have to look at the DW art to see that we see the characters differently.
It would be nice if a DW movie had the effects and the budget of the LOTR trilogy
