One of my Christmas gifts was the Lord of the Rings: The Two Towers extended DVD (to go with the first one). So for the past 3 days, we've been watching a good 9 hours of Lord of the Rings and the behind the scenes stuff.
It's an astounding DVD set, like the first one, but I think they've managed to pack even more stuff into this 2nd extended DVD set. Just like the first extended DVD set, the two appendix DVDs with behind the scenes stuff was fascinating to watch, and really adds a lot of insight into how the film was made, and the decisions the directors and writers made about adapting the book to film.
I don't think there are very many people who are disappointed with Peter Jackson's adaptation to film of Tolkien's great work. This is one of the few film adaptations of a book that's given me a greater appreciation of the book, and where you don't mind the visual imagery from the film interfering with what you read in the book.
