I just finished the book, and I think it will translate well to the screen. I do concur with Andy's friend "J-Man" who felt the book seemed more like a set-up for what is to come (and isn't as strongly anchored its own storyline, unlike the previous stories). But there are some great sequences and unexpected turns, and quite a bit of action toward the climax.
I just hope Ralph Fiennes is scarier than he was in the last one (of course if he'd had John Williams backing him up...
).
