Well, all this gobbledygook has killed it for me. The original COIE lasted for what . . . 25 years before change came? Then came Infinite Crisis which led to a wide open field for stories. But supposedly the DCU had become too complicated for new readers to jump into (i.e. sales were down and they needed something to grab headlines and boost sales).
In just a short time, it's been one Crisis event after another . . . Infinite Crisis, Final Crisis, Flashpoint, Convergence (which affected the first COIE!), and now Rebirth. I'm done.
What I would like to see is someone put together a chart of two different methods of change in the DCU that Rebirth that posters have laid out here. Some say that they are remembering from the post-Flashpoint universe (I disagree but I would like for someone to lay it out in a visual presentation) and others say that they are remembering post-Flashpoint memories (I agree with this but think that this proposal has problems too).
