This is one of the best comics series I've ever seen.
As an ongoing series, perhaps only Preacher surpasses it. And as a relatively
short series (28 issues), it is still readable as a single story.
The trick here is two-fold: an incredible, unique character
in Jessica Jones, an ex-superhero who now works as a private investigator.
Jessica is tough-talking but has a lot of demons that she tries to exorcise
throughout the series.
Bendis's other brilliant insight was to set this in
the regular Marvel universe. So while Jessica's stories are "mature"
and grim, she is interacting with and discovering new sordid sides of
characters we've been familiar with for decades.
