I didn’t listen to the whole thing but skipped ahead for a few segments - movies have almost always had a ‘message’ the difference is that the message of older movies was a message that was timeless. the current crop of movies seem to focus on the current message/angst/cause of the day rather than some truth based on meaningful human nature or God.
There were Commie movies back in the day—but the propaganda was so subtle that modern audiences totally missed it.
The classic example was “Seconds” starring Rock Hudson.
The anti-corporation “message” was not in any dialog—it was only in symbolism throughout the movie.
These days the Commies just try to cram it down your throat.
