I enjoyed it. I was a bit disappointed that it wasn't more like the book, but you have to think they only have a limited time to get it aired before other shows come on, so they have to heavily edit what they surmise to be unimportant or too expensive bits.
It was still enjoyable to watch..but i prefer the book XD
I liked it; I like all the Terry Pratchett adaptions. Of course, they could never live up to the books, because so much of the quality is in the narrative, but I thought they did as decent a job as they could.
