I'm new, so forgive me if this was covered already.
At the end of the featurette, regarding M's passing, the screenwriters and director said that M was always meant to die in this script, because it signaled another transition for Bond, and he had to adjust to a new era.
That led me to wonder if Broccoli and Wilson are in the midst of another re-calibration. Obviously, it is not as radical as the reboot after Brosnan, but there seem to be many changes under way. And if so, why now? The reboot in 2005 has primarily been very well-received. Was QOS's mediocre reception a sign that this reboot had already gone stale, and major re-tooling was needed?
