Gotham is a crime-ridden city with corrupt cops, but the crime rate has been hit hard by the vigilante actions of The Batman. Metropolis is the far opposite of Gotham; bright, uncorrupted, and protected by the super powered hero known as Superman. A hero that, when interviewed by "Daily Planet" reporter Lois Lane, revealed he was an alien from Krypton. But to their surprise, no one, not even businessmen Lex Luthor and Bruce Wayne, believed that statement. Even though someone like Wayne cannot explain how Superman can do what he does.
