What if The Wire were set in Gotham City instead of Baltimore, with Batman in the Omar role? That's the best way to describe this moody cop/crime drama starring the men and women of the GCPD's Major Crimes Unit (i.e. the ones who go after supervillains), in which Batman only makes cameos as a dangerous vigilante whose crazed, costumed enemies are the bane of every cop in Gotham. Veteran co-writers Ed Brubaker and Greg Rucka provide a no-nonsense platform for the "superhero realism" of artist Michael Lark, one of the best in the biz. Start with this volume for its memorably nihilistic take on the Joker.
