I puff my metaphorical cigarette nonchalantly at your distress... welcome to 1986, kids. You'll get zero sympathy from my corner (that's zero as in "Zero Hour") during your little crisis (that's crisis as in, well, every other reboot). Where were your voices when the Penny Plunderer was erased but the Giant Penny remained? Why were you silent when people started pretending that J'onn J'onnzz, who had been absent for the entire Bronze Age "has always been the soul of the Justice League"? Where was your outcry over losing characters when they killed Supergirl or Vibe? Where were you when my DCU was taken from me...?
Perhaps you weren't a reader at the time, or weren't even born yet. For whatever reason, you didn't care about these things, because, well... they were before time. They weren't part of your comic books.
When I was a kid, comic books and associated publications had reprints of Golden Age and Silver Age material in them. It was wild and weird or at least very very different from what I was used to reading. But I was still trained by DC to consider it an important or at least relevant part of "my comic books" and their background.
When the Giant Ants of the Crises came, I didn't scream. I knew I didn't need all those stories "in continuity". They were, after all, still in my head, which has a greater capacity to hold stories than continuity does. Continuity has trouble containing contradictory stories within itself; my head does not. And, who knows, clearing the decks for new stories might bring me some new stories I might enjoy. Which is, in fact, what happened.
You didn't care when the Giant Ants came for someone else's version of the DCU. So now the Giant Ants of the Universal Reboot (and, yeah, I will continue to call it that, no matter what DC tells me) have come to destroy your version of Barbara Gordon. Or the Atom. Or the Teen Titans. Or Superman.
Well, you know what? I do not care; man up. You don't own these characters and neither do the creators who write their adventures; the publisher does. Do I always like what they do with them? No. But I do like the fact that they are, for the first time in what seems like forever, more interested in getting new readers and in going forward than they are in looking backward and keeping old readers (that means you now, kiddies; welcome to adulthood).
You've been enjoying your shrinking picnic in your private little sandbox of continuity for some thirty years now. And now the Giant Ants-- the fiends!-- have come to spoil it for you.
Go ahead and run away screaming the Wilhelm Scream if you want; I'll be laughing at you as you do. Because you, the reader, can, will, and eventually must be replaced. DC knows this, even if you're only just figuring it out.
Or you could stay and welcome our new insect overlords, as I intend to. Because the Giant Ants will win; whether you will win depends on which side you pick, not how hard you fight.
