So, what are we talking about, the business side or creative side? Why are people/readers here talking about business when the cosumers should be talking about why having the universe revolve around batman is bad for storytelling and from world building perspective. What are we? The management? We won't get an ounce of money these corporate companies make from spiderman, batman and superman. So people talking about money like "hah! My side win. Because my character sells more". In fact, we are essentially pouring money into the machine.So,regardless of whomever wins, you lose. So,people should be debating wether the product they bought or the story they are reading is good or not.In this case, why having universe spinning around batman creates bad or good stories as consumers.I guess, this is my humble suggestion to take this discussion back to the creative side as a consumer.
