The not so secret secret is that Hollywood is not really about entertianment. It is about making as much money as possible. It just so happens that making movies that entertain is a great way to do that. And so Hollywood obsesses over what kinds of films make the most money.
That is why we get such a deluge of re-makes of re-makes of re-makes as well as endless sspecial effects driven and violent, retarded stories that feature white males. And that is why we see so little diversity. Hollywood does not believe that diversity sells.
Except that this year it does. Not just the blow out success of Wonder Woman. There are at least 3 major hits — big money makers … that do not fit the current Hollywood formulat.
