With Bruce "dead," Dick Grayson takes over as Batman and is immediately challenged, as his freewheeling, free-talking, press-friendly style catches the attention of both friend and foe, who seem vaguely aware that there's a different person in the cape and cowl. (If I was being snarky, I would point out that Mark Bagley's line art, which draws Bats more like Spidey, would be a dead giveaway if we weren't meant to assume the body shape *isn't* different.)
Judd Winick does a good job of setting up Dick's dilemma--he's got to be Bruce-like enough to pass as Batman, but if he loses himself to Bruce's style of darkness, there may be no going back. I like the idea that he has to change things, while still keeping to the same core that makes Batman work in Gotham. The idea that Harvey Dent would catch on to the duality of the character is a good one, even if it's meant to go away here. I don't like the idea of better Bat villains bowing the knee to Black Mask, but eh, that's not too bad to deal with.
Bagley's art is very slick, as usual, but I don't think Batman is a good fit for him. He'd kill it doing actual Nightwing, though. But as I mentioned above, his version of the character is so obviously different from how we've seen Bruce that the idea he's supposed to be same character is almost laughable. Still, he does a great job setting up panels and I dig his work. I'm just having a little trouble pretending it's not meant to be intentional within the world.
Overall, a good start to this. I'd never read any of it, so it's fresh to me, and I hope the library has more.
