i've been giving this some thought, why is the issue of continuity so important to DC? the reason i single out DC is that they seem to have a pathological need to keep correcting continuity issues (some well deserved ill agree) .
i have always been more of a DC fan than a marvel zombie, but with that said, marvel has almost always glossed over issues regarding their continuity issues and were always prepared to just admit mistake and move on, where as DC almost never seems to really admit making a mistake and try to micro manage a fix with disatrous results (see;hawkman-hawkworld-hawkgod)
COIE has always been a problem for me, at the time it came out i didn't agree with DC's decision to completely change the framework of their universe however i understood why they felt it was necissary. now with hindsight it became apparent (especially in the early years) that although the intentions were good the execution left much to be desired.
but after 20 years most of those problems had subsided, like a rock falling into a pond, there were horrible ripples that had finally been quelled, the lake was placid once again, and it is this time that DC decided to throw another rock in the pond.
i've always felt personally that stories should be the primary goal, a really good story will always trump a story that has to adhere to ridgid continuity concerns.
the punisher is a good example, when Garth ennis resurrected the title, he barely acknowledged Frank's brief time as an angel of vengence and moved on, never has that sorry storyline ever been refrenced again.
im buying IC but i dont really think the story itself is really any good, but i do want to be cognizent of the changes that DC is moving forward with, i just hope that when all is said and done, that in 20 years DC isn't wring its hands at all the as yet unforseen continuity issues IC will inevitably bring with it and will just move forward.
