Sadly, the author of that piece made one worthwhile observation, failed to understand it himself, and then carried on pointlessly for many paragraphs:
it made me painfully aware that for a good many people, movies aren’t art or experience, they’re product. And products date.
It's not the fault of the audience at all. Popular culture simply does date, because it is
product. People who are defensive on the part of popular culture proclaim it as somehow equal to or better than art of real nuance and ambition, and then get bent out of shape when fashion moves on to the next thing.
Well, guess what - people only liked the thing to begin with because it so exemplified the fashions and superficial concerns/attractions of that moment.
Even people who want to own a 1964 1/2 Mustang like the one in Goldfinger
wouldn't drive it every day - it was not designed as "timeless transportation" if such a thing were possible; it was a product appropriate to its moment.
Successful product is not the same thing as valuable art.
People laugh at old James Bond movies because the producers didn't try - or didn't try hard enough - to make them really good. So, they aren't truly enduring.
End of story.
