What are these "levels"? And what agenda do the producers of movies such as Doctor Strange and the Harry Potter flicks have beyond making a zillion dollars? I'll grant you that are political films with agendas, but Harry Potter? Not so much....
Brief example of multiple levels using unrelated content: Suppose there’s a tv show about a hero cop. The cop always wins, always gets his man. We’ve all seen it. The cop is very relatable. Lots of suspense, lots of action. Very entertaining.
By the way, the cop doesn’t like guns.
So here you see the superficial level message is good against evil. Meanwhile the underlying message is guns are bad and good guys should hate them. It’s very key that the audience is never told directly that they shouldn’t like guns. Many in the audience will never stop liking guns. But many others will.
