Batman is the darkest hero of comic world, and perhaps his popularity is due to the fact that he is not a meta-human; he has no special abilities or powers other than his stregth and intelligence, which have been developed through hard work and training. Batman's obsessive behavior gives us glimpse of what would happen if our little obsessive behavior became overwhelming. Or maybe his dark side brings out the dark side of every person. Batman is the most compelling character in comics ever.
