Batman, who got no super powers whatsoever, relying only on his above-average fighting skills and uber gadgets, is a revered individual in the comic world. Superman, on the other hand, is called a pansy by some. So in short, fighting over-muscular enemies with unnatural powers granted by the Powers That Be doesn't gain you respect from everyone. Nah, those people who jeered and booed are just jealous...but black looks cooler then red and blue. Everybody agrees to that..
