I read manga also, and it's because it's more imaginative. Marvel and D.C. are so lame-brained that they can't come up with something other than Wolverine. And all the characters that they DO invent are mostly tired copies; flyers, teleporters, strongmen. We see none of the innovation that Naruto has displayed for the last decade.

Also, when trying to attract young female readers why put a girl in a man-suit? Most girls and women are not attracted to the rough and tumble, fighty adventure that boys are. M. and DC could learn from "Fruits Basket," "The Devil Wears Prada," and "Pretty In Pink."
