Brian Azzarello (born in Cleveland, Ohio) is an American comic book writer. He came to prominence with 100 Bullets, published by DC Comics' mature-audience imprint Vertigo. He and Argentine artist Eduardo Risso, with whom Azzarello first worked on Jonny Double, won the 2001 Eisner Award for Best Serialized Story for 100 Bullets #15–18: "Hang Up on the Hang Low".
Azzarello has written for Batman ("Broken City", art by Risso; "Batman/Deathblow: After the Fire", art by Lee Bermejo, Tim Bradstreet, & Mick Gray) and Superman ("For Tomorrow", art by Jim Lee).
In 2005, Azzarello began a new creator-owned series, the western Loveless, with artist Marcelo Frusin.
As of 2007, Azzarello is married to fellow comic-book writer and illustrator Jill Thompson.
More style than anything else; 100 Bullets reminds me of the animé Death Note in that it's about revenge, but the characters who kill very often never get their own upcommence or grow from their experiences--they don't face any consequences. This ambiguous storytelling lacks any real substance or value, and is a little hollow. It leaves me empty.
