Went to see it last night. For those of you who like the books & films, this one will be a real treat. It was really well done IMHO and included a lot more material from the book than previous films and they seem to have cut less than in others as well.
Overall, it was really well done and thoroughly entertaining. If you go this weekend, I would recommend getting there early and buying your tickets ahead of time. The theater I went to see it at was sold out well in advance (fortunately I bought my tickets two weeks ago). And there was a big line formed well before show-time.
