The "For a long time to come" narration feels forced to the tune of "look, this is epic, you are about to see an epic battle, it's epic, okay? Did we make it clear that it's epic?" It feels stilted the same way that Bendis' not!climax to Secret Invasion felt stilted, with the reading audience being told that Jan's death was heroic but not really being shown the heroic or epic part.
...Or it might be that Genocide's costume still prevents me from taking this seriously, although Genocide's eyes are effectively creepy. Maybe she would have worked better visually if she'd never had the astro turf strip on her eyes to begin with. I do, however, look forward to Diana finishing Genocide off, because then hopefully she won't return to continuity anytime soon.
