It's not often talked about here, but Deathstroke is the best book that DC proper is publishing, for my money.
Rarely do you see a book with such rigorous attention to detail and such intricate, yet inevitable, plotting. Every character in this book is a monster, but they're all human monsters, and of different sorts, endlessly fascinating, surprisingly sympathetic, but finally brutal.
There are no easy answers, no pat moments or reveals, characters are driven by a hundred competing internal and external forces....
Priest is doing top flight work here, some of the best of his career. The best since Black Panther.
Everyone should be checking this book out. But if you can only pick one, check out the issue he did with Denys Cowan, about gun violence. Too often these become reductionist afterschool specials, but Priest has a hard look for most everyone involved. And even if I disagree with the politics that seems to be the heart of his belief on this (respectability politics), the craft with which he explores the situation is just awe inspiring. One of the great minds of comics.
PS, his Batman two parter was probably the best use of Batman I've seen since Morrison was on the book (and completely different).
