Thanks alot!
So first they write something,then they delete it,then they bring it back again?
This is why they never just adapt a Comic book for the big screen and they always make their own stories.
I look forward to trying to figure it out.
Actually, they never adapt it straight from a source because they normally don't care about the source material in my opinion. Not just for comics mind you, but everything.
WARNING: the following is really geeky.
To sum up several several years of comics in on simple error laden paragraph just waiting for the Simpson's comic book guy to step in:
DC (detective comics) didn't quite start out like Marvel Comics, i.e. one company to rule them all, but rather a conglomerate of comics. Detective Comics themselves brought on Batman, Action Comics created Superman, Wonder Woman was under another label, Whiz Comics had Captain Marvel etc. So as DC started to grow, they started to assimilate several other comic's properties under one house and universe. Suddenly the Flash was hanging out with Supes, Wonder Woman's stupid invisible jet was flying over Gotham City. Everyone was integrated and the DC universe was first truly formed. Then Marvel came about and DC had its first contender. Having to compete with not so perfect heroes, DC revamped several of it's main heroes from the big three (Supes, Bats and Wondy) to the others; Atom, Flash and Lantern to name a few. A few examples: the original Atom was a guy with "super atomic punches", new Atom could shrink to the sub-atomic level, the first Green Lantern was empowered by a mystical ring whose weakness was wood... the new Lantern was part of an intergalactic police who's weakness is the color yellow (yeah not much better). You had a new age Superman who's in his 20's during Kennedy's presidency and the original Superman who fought in WWII in his 20's. Soon all these time and dimensional barriers are broken and duplicates are everywhere, 40 year old Supes is teaching 20 year old Supes lessons, yadda yadda, newer readers are confused.
So in the 80's, when shoulder pads on superheroes was cool, they took initiative to clear up the mess. Crisis on Infinite Earths was an epic story that erased all universes and characters who didn't matter or were duplicates. But instead of just stopping there, the editorial staff took it upon themselves to rewrite most of the heroes to appeal to youths once more (because god knows the fads in the 80's are the ones that lasted, wait, where's my Swatch watch?). All of the classic history was completely destroyed, Superman was depowered to mere superhuman levels that could make him potentially be beaten by Spider-man, Supergirl was a gooey matrix, Brainiac the alien supercomputer was a psychic straight from the circus... So fast forward to now. I've gotten fatter. Much fatter. And DC has decided the huge overhaul wasn't necessary. Multiple universes, classic DC history and characters are all back, most of the duplicates and confusion is still left behind. End of my long and unnecessary story.
