I’ve always thought that prior to Casino Royale there was a sort of soft reboot element to the James Bond series every time there was a change of actor. OHMSS admittedly has a sequence where Lazenby looks at gadgets that Connery used, presumably to stress that, his “this never happened to the other fellow” line notwithstanding, he’s the same fellow. DAF, in which Connery returns, pretty much ignores OHMSS. LALD, Moore’s debut, eschews Q and a lot of the tropes. Dalton is clearly not meant to be the same fellow as Moore, I terms of age, attitude and delivery. Brosnan mixed elements of all his predecessors but is clearly enjoying being an agent much more than Dalton did. But for all that, there’s consistency of Lois Maxwell as Moneypenny for 20 plus years, Q returned after LALD & assisted 2 more Bonds and there were nods to the ending of OHMSS a few times, while DAD (which ended up being the last pre-full reboot film) has another sequence acknowledging old gadgets etc
