Before I realized that I would literally not have the time to reread Breaking Dawn before the movie, I decided that, for once, I would skip this step. I've decided that this would only make me more focused on how the movie is different from the book, and that probably isn't the best approach for material like this. Instead, I'll be looking for two things in the movie: tone and characters. I'm sure I will still miss lines and scenes, but I will at least try and keep my "analysis" broad enough that it is focused on the right things.
As far as character, we must obviously see a transformation in Bella, physically and in terms of her maternal instincts. Also along these lines, Edward gets his fatherly side, and he and Jacob become closer in their brotherhood of sorts that began in the first part of the book. Moving further along, Alice becomes a central figure again with her visions and her departure with Jasper. Then comes the tricky part of characterizing so many new faces, though costumes will help this greatly. All these new faces are at least going to look different.
Tone goes through quite a journey--a journey that will probably make this a movie more friendly to audiences than Part 1. First comes the sense of fitting in, then the parenthood, and then the fears. Fears about Renesmee's future, the Volturi, the situation with Charlie, the mass coming together of so many vampires, etc. Then there is the feeling of power in unity, the mental preparedness that allows the Cullens to convince the Volturi. On this note, I'm wondering if that final scene will end up more action-based; it would seem strange to me if it does since Stephenie has talked about how the chess scene book cover represents that it wasn't that kind of battle.
Two other things I am very curious about are Renesmee and Nahuel. What we have seen of Renesmee so far has been wonderful, so I'm getting the idea that these two very important characters will come across just right.
I'll be seeing the movie (early) Friday morning. I make no promises about posting my reaction on Friday: I tend to like to wait until I've watched twice, but I don't know if or when that will be. We'll see.
