I'm personally more than a bit freaked about this reboot, relaunch, whatever you want to call it.
Mostly because of a picture I was shown of the JLA... a rather young JLA with many members looking to be in their twenties. WTF, DC!
I mean, I get their desire to show the begins of this new universe/timeline, flashing back to when the team was energetic, full of hope, and zealous, but really? Why do they have to go all the way back, wiping out several decades of character growth, world development, and more than that...
What does this mean for the younger generations of the DC universe?
The characters that helped ease more than a few new generations of comic book readers into DC comics or reintroduce us after we've been away so long. While Wonder Woman was my first exposure to comics, it was the younger counterparts, such as Batgirl, Supergirl, Robin!Dick, and Wonder Girl that made me stay both when I was a kid and during my more recent return. I've even grown to really enjoy the newer characters, including Superboy!Connor, Tim Drake, Damian Wayne, Miss Martian, Jason Todd, and so on.
DC has built up several amazing amount of new and interesting generations of heroes within the last three or four decades, enlarging and enriching their existing superhero families, groups, and the universe as a whole. They, imo, have been key to forming and strengthening the core to the DC universe nowadays, and it seems like DC is just carelessly tossing all of them aside like they are pointless.
What happens to these characters? Will they return as the timeline continues forward, i.e. a series of Robins to fill the partner/sidekick role of Batman? Or will all these younger heroes cease to exist? Will there even be sidekicks in this new, rebooted universe? Will there be a Teen Titans or Young Justice?
The answer whether I made the right decision to return to reading comics and probably whether I'll be sticking around any further.
