It’s very true the film industry and many other businesses sell BS in one form or another–but as long as the world is buying–there will be a market–via theaters, streaming, or otherwise.
Most Hollywood types don’t take it all too seriously. They know escapism, in its many forms, will always be in demand as long as there are human beings on earth, and they are simply enjoying the ride for however long it lasts. Right now, that’s 100 years and counting.
