Eh..... My problem with it was, not much seemed to happen. The whole issue largely consisted of seeing people rise from their graves (a number of which, apparently, as unnecessary leads into the various minis) or zombie DC heroes being all "RAR! We RZ unhurtzable and unstopzable and there iz nothing you can do!". A large part of my lack of enjoyment may have come from the fact that Aquaman's mythology doesn't really appeal to me. I couldn't care less about the drama around Aquaman and Aqualad and Miss Aquaman and Aqualass, and since that took center stage, I largely just didn't care. Besides which, the end result of it was just that all of Aquman's crew are zombies. The Martian Manhunter fight, which is now spread across two issues has entirely consisted of "This zombie is so badass that nothing can so much as scratch him". It just felt like it was just, like, treading water while the first issues of the minis drop. Nothing was accomplished, not much was discovered besides what we already know. It was just so much fluff.
Okay, with the negatives out of the way..... That doesn't mean I'm going to stop reading this book. I felt like it was a disappointment as an issue, but it certainly doesn't condemn the series to failure. The high concept is rather interesting. The structure is sound. I like the idea of Blackest Night being the event itself, while Green Lantern focuses on the personal struggles of the individual Earth lanterns, GLC focuses on the cosmic event spinning out of Blackest Night, and the individual minis touch on the impact of death of the various major DCU heroes. Even if the event itself is a flop, it's still an opportunity for the individual minis to touch on the effect death has on these individual characters. And the prose back-ups by Johns look like they'll do an interesting job of refreshing new readers on relatively minor DCU characters who are going to have a large impact on the book. I'm curious to see which centerpiece character personifies rage (Spectre maybe?). I'm betting money on Ralph and Sue as "hope". And finally, Ivan Reis' art is really pretty. That page with zombie sharks chomping down on the Atlantean guard is just wicked awesome.
I'm not giving up hope on this book. I have a feeling it will ramp up once we get deep into the actual plot. I haven't found the first two issues particularly compelling, but they've been entertaining enough, and we're only a quarter of a way into the series.
