Art (movies, plays, fiction, paintings, poetry…) exists to create a change. Often, that’s a change in the viewer, and sometimes, powerful art changes the culture.
Art with no intent can entertain us, and it can also reinforce stereotypes and simply help what is in our world persist.
Art with selfish intent exists to manipulate the viewer to serve the needs of the artist. It doesn’t often spread, but when it does, it can have a corrosive effect on the world around us.
But art with generous intent is different. It might not address an issue the way you would (in fact, that’s precisely why we need it) and it creates tension as it helps us look at things in a new way.
