Bond is its own massive exception since, really, every movie is a reboot. It was never serial, so it kinda doesn't really fit the whole model at all, so no I don't consider any Bond movie a "reboot" as it's not the kind of series that can be rebooted.

Of course it's subjective, and of course you can find exceptions. But "attempt to start a new timeline that is whole without need of other series that came before it" I think is the most complete generalization that covers most cases.
