I will be sure not to spoil anything for you. I will say, you have a lot of fun to look forward to, and your assesment of Book 3 and the movie is a common one.
I am really looking forward to the next movie, they have a lot of editing to do.
No kidding. It looks pretty intense, too. Have you seen this bunch of clips?
