Blackest Night has been years in the making, and looks like it might actually pay off. Issue #1 was good, creepy stuff. The panel where Green Lantern rings up all of the DC Universe dead, shown below really points out how casual DC's disposal of their superheroes has been over the last 25 years or so. That's not even counting what I'm sure is easily three times as many villains, and countless supporting cast. The ending was quite distressing, but effectively so. I wasn't really expecting much from this, but the first issue was a good start.
The question remains; Will they use this as an excuse to resurrect a bunch of characters? Any of these guys? All of them?
An important point: These zombies aren't zombies. Zombies have a whole set of rules that Black Lantern Ralph and Sue Dibny weren't following. These Black Ring entities are possessing the bodies, manipulating the bodies, and mimicking the former occupants, all the better to be evil, but they aren't zombies.
It's okay, kids, that's not Golden Age Superman ripping out Krypto's heart, that's some...thing using Golden Age Superman's body like a sock puppet!
For awhile there, Neil Gaiman's Death was the personification of Death in the DCU, but that hasn't been the case in some time. I think they've also tried to suggest that the Black Racer "was" Death, but that never really stuck either, and regardless, he's off the table now too. The fact that there's really nobody to usher the dead into the afterlife these days may play a part thematically in Blackest Night.
I will be very disappointedwithout an appearance by Driq of Criq. Driq was the (ahem) short-lived zombie Green Lantern introduced in Green Lantern #217. Driq was great, by the way, a Green Lantern so learned and valuable that his ring wouldn't let him go after he died.
