A good chunk of this bitterness would subside if Jon turned out to be the son of Superman and Wonder Woman when you get down to it,I didn't see anywhere near this level of bitterness towards that Wonderstar character that turned out to be Magog all along,it's no secret why. Looking at these boards I often think Superman should stick with just a Superman book because his own fans want to tear down his world. There's no point in having an extended family/line of books if haters are just going dismiss them. DC makes it worse by having different versions of the same characters in their attempts to please the haters.
Whatever Supes they use post Rebirth I hope they stick with him,dont change the character to satisfy the fantasies of shippers and insecure fans,give a balanced and well rounded take on Superman that incorporates the best of his character from the decades of history.
