Each Bond film is the exact same movie, but the series has established that formula pretty well. Schlocky action, cheesy one-liners and a general feeling that it should not be taken seriously. Audiences go in knowing and expecting that.
You could say the same thing about the MCU.
You could. The Marvel formula is pretty well established at this point. But I don’t think the brand sees or markets it’s movies that way. I also don’t think the general movie going public sees the MCU movies that way or else there would be no appetite for them anymore with 3 or 4 of them every year.
The supply and demand for Bond is a lot lower because I think most people recognize that all of the movies are the same.
Getting back on topic a little bit, it’s possible that interest is waning in Star Wars films because the public is recognizing that the new movies are afraid to be different and keep retreading the same already well-trodden ground.
