A sprawling storyline involving Gotham being shut down from the rest of the world after a series of cataclysms, with this picking up a few months after the borders have been shut down. An interesting way to get Batman to have to operate in new ways--since gang warfare breaks out, his usual tactics just don't work in here. I wouldn't be at all surprised to hear that both The Dark Knight Rises and Arkham City used some ideas from here.

Fantastic character work in here--Bruce Wayne, Barbara Gordon and Jim Gordon all get some character building and introspection in here, it's not just action sequence after action sequence. I rather enjoyed Huntress' storyline and the way that panned out.

I was dreading Azrael when I realized he was included in here, but luckily I really like what they've done with his character. He's still not a favorite, and doubtful he ever will be, but after his stint as a homicidal and self-righteous Batman really anything is going to be better. Even Azrael has some excellent character development in here.
