Did we read the same book? Now I agree that CR was faithful to the spirit of the Fleming novel (especially after DIE ANOTHER DAY,) however it's a bit absurd to say it is any more faithful than LIVE AND LET DIE, THE LIVING DAYLIGHTS, OHMSS or the early Connery films (I'm not saying you specifically said that, but many current Bond fans tend to.)
CR was originally a spy-thriller, and a cold war mystery novel set in the 1950's, whereas the movie is a big budget, action packed extravaganza set in 2006. Obviously the filmmakers couldn't be that faithful to the novel and keep the modern setting. Sure, the very basic plot of the novel is kept intact, but pretty much everything else is changed.
I would say CR is about as faithful to it's original book as the 1943 PHANTOM OF THE OPERA and the 1931 FRANKENSTEIN were to theirs: the spirit of the novel and the basic plot are the same, but that's about it.
