Well, I didn't say I wanted it, exactly. But -- and I say this as a guy who loves Roger and counts him as his favorite Bond -- if you're bound and determined to build your action movie around a 57-year-old leading man, you either acknowledge his age and use it in your favor, or you ignore it and make the whole enterprise look awkward at best and laughable at worst. The best option would have been to let Roger retire with OP -- a great film that fit his strengths -- and start a new actor in AVTAK, which in turn should have been re-thought itself. So much of this movie feels like just going through the motions, from "let's get Roger again" to "let's find another variation on Oddjob" to "let's borrow the villain's plot from 'Goldfinger'" to "hey, it worked last time to hang Bond from a plane, this time let's make it a blimp." There is no life or spark to AVTAK, and the living, breathing avatar for that sense of tiredness is poor old Roger. A new Bond might have led to some energy on other levels as well. But if you're going to put Rog in the movie, don't pretend he's still 30. It's not fair to him or anyone else.
If I could change history, my "want" would be for AVTAK not be on Rog's resume. For his sake.
As for NSNA, the "getting older" bit figured at the beginning of the film but after the Shrublands scenes, it's dropped and never picked up again. NSNA is another film made without much of a plan or any kind of tonal consistency. But to the extent that age is a factor, it's because the film's made not by EON, with their vested interest in keeping Bond supernaturally young with interchangeable faces, but by a rival company who knew the one ace in their whole deck was Connery. The entire film is based on the idea that Connery is the one, true Bond, so by making his age a talking point, they reinforce the idea that he's been off doing something else all these years while we've been watching imitators.
And as I said before, letting characters age with the actors works for Star Trek, but it doesn't for Bond, at least not Bond as EON's chosen to define him. Specifically it hasn't worked with Craig, who went from too young and reckless in CR to too old and "past it" in SF, then back to the pink of health for SP. The age thing is probably a subject best left untouched, but the best way to avoid it is to never feature a lead actor older than 50. It might be intriguing to imagine how Bond would handle aging, but it's not a recipe for keeping a franchise going. And the answer is he probably wouldn't handle it well, anyway: Bond should die young(ish).
