I'm totally with Alatar here, but then I'm no purist; I stopped watching Bond movies in the cinema some time around 1986. And I never watched any of the Pierce Brosnan ones until a couple of weekends ago. Still, I think that Casino Royale has definitely reinvigorated the series, which had been gradually pushed into a corner. Remember, the Bond franchise now has very narrow manoeuvring space between the new type of spy movies (Bourne ID, xXx) and Austin Powers. Doing a Moore-type, suave Bond would be far too close to Powers-esque caricature.
