Everything about movies, down to the ambience of the theater itself, is a perfect setup for brainwashing. This means there is much more than meets the eye. The effect is also very strong when you’re in your living room watching tv.
So when the audience “understands” a given movie to be fiction or fantasy, what they understand is just the surface level. Beneath this are many other levels. Changing the way people think and behave has been an active agenda on the part of movie makers since the very beginning.
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....
