I could use an analogy about movies, just to insult Transformers, but I won't. The audience decides which qualities they want to embrace. It could be fun factor, graphics, community, or what have you. With movies, it could be an actor, plot, plot twist, premise, or whatever. The people decide if they want to be blown away by dumb fun or if they want thought provoking content.
And I agree. Quality=/= sales.
