Basically everything that can date Bond film very quickly is gone.
Pierce Brosnan has been replaced by a young-ish Daniel Craig, there is no Q, no campy gadgets, no silly naked women silhouettes in the opening credits, no world-dominating super-colossus villains, no Miss Funnyfanny (or whatever), and no silly one-liners after killing bad guys. Casino Royale is a major step-up from the flamboyant Die Another Day.
