Because of his personality is to boring and self rightous? i noticed something about characters with super powers like Supes they have more of a catch to thier attitudes by projecting that towards others which is why they're liked more. The most clear example is the Smug Super, a arrogant and mean spirited rebel who has no respect for authority or rules and is a jerk who thinks himself as above everyone yet doesn't stray from doing the right thing. Superman however is a humble than thou ideal and a boyscout who follows the rules and is more than to perfect(not saying he is just implying based on something conceptions Superman is known for). Is that why most fans prefer some characters like the Flash or Guy Gardener over Superman because even though thier powerhouses in thier own right, they have more value as cocky characters which sends out thier flaws more than thier strength and idealism?
