Batman is unique among members of the Justice League in that he's merely a normal human being who utilizes somewhat advanced gadgetry and detective skills to fight crime. This means that many of his stories - namely the best ones - focus on his more down-to-earth and realistic nature. Modern stories have sadly whittled away at this vibe, though an old-school series proved that it was the best way to handle the Caped Crusader.
