There's a lot of good action sequences here, but this book suffers in comparison to the monthly Earth 2 book. There, we had amazing action but we also got a number of good character-building scenes. The closest we get to that here is the implication that Lois "Red Tornado" Lane really hates zombies because they remind her of her own status as a dead woman's spirit in an inhuman body.
As before, the artwork is all over the place. There are a number of artists with a number of conflicting styles and the final effect is not a positive one. Stylized renditions of our heroes clash with more realistic artwork and naturalistic action scenes look awkward next to more forced poses.
On the whole, I see little reason to pick up this book unless you, like me, are deeply interested in the final fate of Earth 2. Even then, the lackluster artwork may drive me away from this story. I really wish DC Comics would assign different art teams to individual issues rather than having multiple artists doing a few pages in each issue of these extended series.
