My hype meter is probably at about 40% and heading downward.
1) Rebirth itself has been interesting when it has been far away from navel gazing. So far things like "The Button" and "Superman Reborn" were full of sound and fury but really didn't move the ball much.
2) This is the lynchpin supposedly of just what happened to the DCU and it's been coming for so long that I can't believe anything could live up to the anticipation.
3) This is also the 3rd "redefinition" of the DCU in just over a decade (Infinite Crisis, Flashpoint, this) so I'm wondering just what they are going to do this time that actually doesn't feel like a retread of past events.
4) Has anyone gotten the Watchmen characters "right" after Alan Moore and Dave Gibbons penned that last issue of the mini? And is Johns really up to the job? This isn't an attack on Geoff's overall skill as much as wondering if this is really in his wheelhouse. I enjoyed the Legion Final Crisis issues more than Morrison's actual Final Crisis but on his best day Johns' stories read less like Alan Moore than Morrison's worst stories. And I'd rather read Johns' doing his own stuff rather than trying and failing to recreate voices from almost 30 years ago.
