This kind of show is just distraction from reality and the Real Thing. Escapism, if you will. Isn't this all Hollywood is about in the end?

As a European child, decades ago, I did not understand those American movies. Now I know the extent to which American society has been literally shaped by the First Commandment of Hollywood: The Show Must Go On. You can see it in the way people in the US talk to each other and behave.

This explains why there are even movies about movies and actors. Think of a recent movie from Quentin Tarantino (as a case in point). Why the heck would people go watch a movie about movies and starring actors as themselves?
