First off, Batman Begins was in flashbacks? I haven't seen it in awhile but it didn't look like flashbacks to me. Did I miss something?
Ok just as many people know Batman's origin as they know Superman's. There is still a new generation that probably knows nothing about Superman. I still don't know why people think everyone knows everything about Superman.
I think Superman definitely needs a reboot, beginning story. Something that SR should have been. I think that is what bothers me more than anything about SR. It was such a wasted opportunity.
Someone can correct me if I am wrong, but SR is the only Superman project I can think of that did not do a Superman origin story. When you start from the beginning then you can create your own world with your own conditions. I will never understand how anyone that is suppose to like Superman so much that they would not want to tell their own Superman story.
As far as the people that want Superman depowered, that is not Supes, that is some other hero like Hellboy or something. Superman is Superman. If he is just too powerful for you then you might want to see something else. That is who Superman is. He is not basically Hardcase or Wonderman, he is Superman. It would be like making a new Batman movie and having Bruce build a suit of armor like Iron Man to fight crime because he is going up against superior foes.
Superman also is the example of what a hero is. He is a hero to all. The world loves him. His parents love him. He has a woman that loves him. He has friends that love him. He has the ability to save others and that is what he desires.
Superman: The Animated Series showed that you can do a Superman story with him still being Superman, yet being tested by the type of world we live in today. I am sure there is someone out there who can tell that story.
