Again, I wonder whether it would do the Bond films a service to continue exploring the character.
In CR and QOS, yes, that worked. In SKYFALL, okay - the "am I too old, washed up for this, can I stay loyal even if I am disposable, and my surrogate mother dies, where does that leave me" worked, too. Although the answer to all these questions was not a surprise at all, therefore the inherent drama was kind of pretentious and forced.
In SPECTRE the "can I live outside of this profession" seemed to me more like an afterthought, but I´m willing to say it added an additional layer to the character. However, do I want Bond to continually doubt himself and his life?
Rhetorical question, this.
No, of course not. I want Bond to enjoy his life, to see meaning in his job and to have made up his mind about it a long time ago.
So, which angle can still be exploited to explore the character? Can the character actually be explored more? Should he be - or does this only lead to a weakening of its impact, turning him into - yes - a Bourne-like figure, always at odds with his past and therefore his present?
To me, Bond films only have a future if they set themselves apart from other spy fare, especially the Bourne series. They must not try to give Bond extra layers because that would take away from the character´s appeal: that he is a cool professional, living his life to the fullest.
As for the Craig arc - if it continues after SPECTRE, there seems to be only one way forward: another confrontation with Blofeld, the discovery that a life with Madeleine is impossible and that he is condemned to be and remain a spy.
The Craig Bond, it seems, can only really be about revenge for Vesper and what she stands for: a "normal" life taken away from him (and in a way because of him, since he chose the profession before she met him and therefore endangered her as well).
But - do I want this in another film that mainly will tread water, showing me Bond coming to terms with what he is?
No.
Move on, EON.
