IGN has a script review online. According to the author, who has evidently read (and moreimportantly understood) the novel, the script does follow the book in most of the key areas, although it does water down one or two important aspects. Still, based on this review, I'm moving my interest up one notch to "mildly interested." Hopefully some new developments, or even an early trailer, will move it up to "cautiously optimistic."
