So something that has been bothering me is the fact that Batman in BvS is almost unknown at the time of the movie. The police aren't his friends yet, they think he's fake, and so do the newspapers and all of Metropolis. Yet, there is still the "bat signal". But unless he turns it on himself, who does it? No sign of Gordon, no sign he's working with the police. And he's obviously been doing this awhile, seeing as how Dick Grayson bas probably become Nightwing by now, and the Robin suit we see is Jason Todd's. Yet, there's still no signs that the city knows what he is, who he is or that he even exists. Clark makes it sound like it's a new development, by basically saying there's rumours of a bat vigilante. It just doesn't make sense to me that if Batman has been doing this for so long, and put the Joker and other big time criminals away, that the world wouldn't know about him.
