Unfortunately, fixing the Marvels would, in the minds of current DC Editorial, necessitate another "Event," one in which countless iterations and sub-classifications of the Marvel family members all converge to somehow resurrect Shazam or sunder Freddy from the "Magic-Lightning-Force" or whatever...

Another editor would rush in to hitch his Creeper revamp to that rising star, and another would sagaciously rub his chin, recognizing the theme of this New Event as "Reinvention" and begin making a list of characters DC must mix into this juicy stew... The New Internet-Age NewsBlog Legion!... Vartox's Hot Momma Replacement, Vertex!... Razor-clawed, badass Shrieky, the Super-Cat!...

"My God!" they'll all begin to keen and shudder at the Editorial Retreat plotting session, "W-We can't fix these characters yet! There's still so many pieces left for them to be broken into!!!"

Plus, as it turns out, fans, especially convention goers seem to really like the idea of Mary as a bad grrl  in a tiny, pleated PVC mini-skirt.

If that were undone, someone there would re-do it in a hot, Mister Mind-sized minute...

Goyer's involvement in the Superman film has now rendered that a complete non-starter for me.

Superman as a politically naive thumb-sucker casts no allure for me whatsoever.

I remember there were some pretty good pre-cris stories, as far back as the seventies, where Superman had to balance his moral support for certain causes with the knowledge that his superpowers and his need to seem neutral in order to be able to do the job of protecting the planet limited his ability to interfere.

There was a story where an old Native American was protesting the building of a polluting factory on holy tribal land, and he was drawing magic coloured drawings in the sand to call on the spirits to protect the land. And seemingly they responded, with Superman stopping avalanches and earthquakes that resulted. Until it was decided to leave the land alone.

Whereupon we learn that Superman has secretly been helping the old Native American by causing  "the work of the spirits."

The Pre-Crisis Superman would have gone in to the protests as Clark Kent, Foreign Correspondent, and might have used his powers more subtly to  diffuse tensions and protect protesters.

Going in there as Superman was just grandstanding where Superman might get credit for "sticking up for the protesters", but to some the protests would lose credibility and the government claim that it was all part of American agitation would be validated.

That's the real reason it was a bad idea to go in publicly, and the real reason the Obama administration should ask him to stand down. And the reason I call the story politically naive.

Glen,

As a one-off tribute issue to that horrible day, and the brave people who lost so much.

If 9-11 had occurred in either universe, maybe one plane could have reached it's target, but certainly not three!

With universes filled to the brim with telepaths, sorcerers supreme, time travellers, and even cross-time travellers, it'd be hard to imagine any disasters, natural or otherwise, ever occurring. 

9/11 would have been halted before the planes even left the ground.  The Holocaust, The Spanish Inquisition, The Salem Witch Trials, etc., as well. 

We'd probably wind up living in a world like the one portrayed in Minority Report, where crimes were stopped when they were nothing but passing thoughts or the vaguest plans in the mind of someone who may or may not even carry them out.
