I still think the "I'm not too old for this shit" mood of NSNA is fun to watch. It don't take itself seriously. That's why so many Bond fans don't like this movie I believe (like most of them don't like much R.Moore humor). I am not a real Bond fan (Casino Royal was quite good though) so maybe it is why I like this one!
But... I am french, and very often in the late 70's early 80's the guys who were doing the french voices made crazy stuffs with the dialogues (most of the time some welcome humor, adding lines when the actors turn their back to the camera, etc... but always with respect of the movies mood) . Star Wars OT in french is almost better than with the real actors voices. I suspect NSNA had a good "french treatment" on the voices.
Now the french versions are quickly and poorly done these days. The prequels with french dialogues are even worse than with the original voices (if you can ever imagine such a thing).
