Counterpoint: when was the last time a Bond film was culturally relevant? They have stuck stubbornly to the same formula (handsome while male actor, quippy dialogue, gadgets, Bond girl, supervillain with genius plan, title song, etc). The tropes were so well worn even the parodies have parodies at this point. And Brosman and Craig's attempt to "modernize" were very shallow adjustments. Which is why each Bond movie comes and goes with little fanfare. A blip of discussion on "who is the new Bond girl?" Or "what will they do different?" That eventually boils down to a mediocre box office and is quickly forgotten. It's been that way for 30 years at least.
That's what happens when you don't attract new people. You stick to the well worn formula. It becomes stale. Bland. Forgotten. The IP equivalent of a McDonald's on the highway: you know what to expect, but you also know it's not going to wow you.
So the question becomes: at what point do you decide that an IP should opt for McDonald's and be safe, reliable and boring? We already complain WotC is adverse to risk, but at the same time people demand they play the hits and don't change the formula. Don't just make another Moonraker, make Moonraker again with better set work.
