I think consumers in general can't understand subtlety. That's why I strongly advocate that anyone with a point to make should make it as hamfisted and on the nose as possible, just straight up beat the viewer the viewer over and about the head with the point to the point of directly telling it to them. That's not to say that all art has to do that, but that if one wants to convey a message with it it should be as clear and direct as possible.
