Few graphic novel series are as beloved by violent comic fans than Brian Azzarello and Eduardo Risso's 100 Bullets. I have only gotten through four of the thirteen highly stylized and complex books. The first one sets up a fairly simple premise: One Agent Graves finds people with rightful grievances against someone and gives them a suitcase with irrefutable proof of who has done them wrong and 100 untraceable bullets that have no consequences with the police.
Soon, in later books, things become more and more convoluted and sometimes the art (which is not always my favorite) can make it more confusing, for a little bit I was mixing characters up, but it is a series that gets better with each twist and turn and added layer of plot.
Azzarello has had a classic comic book career. He's written for Spiderman, Batman and since 100 Bullets has authored other series like Loveless and Deathblow. While this is not particularly my graphic novel cup of tea I am more a fan of the less typical and gentle work of Daniel Clowes and Chris Ware, these books have expanded my horizons and fans of dark graphic novels should certainly not miss these.
