It’s also why characters in mainstream movies now simply say less. The last thing any nervous producer wants is for their blockbuster to get banned because it brings up something dodgy. Better to spray a field full of pesticides than sow it with words that could sprout into hot potatoes.
But these films also need to appeal to a generation for whom actual chat makes up a diminishing proportion of their communication. Each new app encourages us to whittle. Emojis and Instagram promote pure imagery. And people like pictures in part because this is an international language. Everybody understands what a little picture of putting on nail polish means. Why explain further? Nuance only contracts the scope of the conversation.
