Movies do have power. More than books or even TV. Why is that? It’s the art in it. The ability of the artists to put emotions into memorable images. It works as books once did.
Back in the day some books changed the world. The Bible, Mathematical Principles of Natural Philosophy, The Starry Messenger, On the Origin of Species, Uncle Tom’s Cabin and The Jungle. Upton Sinclair wrote The Jungle in 1906 and it is the last book I can think of that had The Power. And it was just about then that movies began to surpass books as our main source of entertainment.
It is the ART that Republicans can’t stand, it is the ART that drives their hatred of Hollywood and it is their lake of ART in any aspect that keeps them old and stuffy and boring.
