Good, but not as progressive as a gender-queer vegan trans-woman Bond with a graduate degree in post-colonial studies.
On a message board that will remain unnamed I saw someone argue that the next Bond needed to be a woman because gender is socially constructed; he later admitted he had very little familiarity with or interest in the series.
I think Craig will probably return for a last hurrah. As for the age of who will follow him, I also think early to mid-30s is a good age to shoot for--Fleming repeatedly describes Bond as "young" and "strong", so you want someone who has a note of youth but looks tough, so no baby-faced DiCaprio types. It's also in the filmmakers' interest to maximize the amount of time the actor can look convincing in the role by casting someone at the right age. Connery, Lazenby, and Dalton are all good examples. Moore was a special case, since he initially looked younger than his age, but he did at least one Bond film too many. On the other hand, even without AVTAK he would have tied Connery for official Bonds.
