I think there is a general trend towards more realism. While Burton's Batman maintained a bit of a comic-book atmosphere Nolan's Batman doesn't.
This has many obvious advantages but there is something about a film emphasizing that it is a film. When you watch old silent movies they are of course less realistic than 'talkies' but precisely via emphasizing that it is not just a 1:1 copy of reality a movie can express itself.
I think in the case of Bond that's the, as Livingston called it so wonderfully, "shaken not stirred".
PS: While we are at it, I think that ST09 evaded this trade-off and achieved more realism without abandoning the sense of TOSish cheesiness and don't-take-yourself-to-seriously.
