Personally I think it's something of a fallacy to suggest there was some golden age of serious, gritty Bond films starring Connery. There was From Russia With Love and...
Well that's it. This is a film series that began, after all, with Bond facing a mad scientist with metal hands who owned his own island, had his own nuclear reactor, and who was toppling rockets using radar beams, its not exactly John le Carré. FRWL is the exception really, then we're back to the fantastical again with cars with machine guns and ejector seats fitted to them, madmen with "lasers" and diabolical plots involving atom bombs. In the next film Bond's got a rocket pack and in the next one we have a villain with a hollowed out volcano and a spaceship that eats other space ships!
After FRWY the next time Bond was remotely grounded in reality was probably FYEO.
Or sure the preposterous nature of the films varied. OHMSS, LALD, TLD and their ilk are very different beasts to TSWLM, Moonraker and DAD after all, but at heart they're pretty much all preposterous bar a few exceptions.
But that's fine, I like a touch of the ridiculous in my spy thrillers
