think on the bright side, that may have been the original intent, but as we all know now....thats not what happened
thankfully, I wish DC would grow a pair of balls for once and actually have Superman outright beat Batman, I mean sure we have plenty of stories where Superman has beaten him, but there has always been a catch such as Batman is corrupted by power, Superman in mind controlled etc. The Dark Knight Returns has them both as themselves knowing full well whats happening and what they need to do.
If Batman is someone who can beat Superman then by all rights Superman should get a story where he outright beats Batman. The whole issue of that was Superman is so powerful, who can beat him? Great now we get an idea that under those circumstances Batman has a real chance, but what does that do at the same time? Shifts that question to become "who can beat Batman?".....answer.....Superman.....now lets see it already
