This is a sprawling, ~~semi~~ full-on abusively erotic (see EDITs below), sci-fi / post-apoc series which also has philosophical and dreamlike overtones. Like many Italian series, I find it hard to make sense of it all, altho to be fair I've only ever read a couple of the stories in the classic Heavy Metal / Métal hurlant magazines.
Altho I'm not opposed to some eroticism here & there, the two things that make it hard for me to get in to this series (officially called Morbus Gravis) is that every single album is evidently sexual-themed, and that Druuna the character is largely passive... and generally the sexual pawn of others.
In terms of positives, the cross-hatched line & watercolor art is pretty fabulous, and I salute Serpieri's imaginative concepts and plot turns.
I doubt I'll be posting much more Druuna here, but wanted to share at least one.
EDIT: Due to the valid rebuttal below, I'll link to the WP article, which pulls no punches in detailing the more sordid stuff. [HERE]
EDIT2: Interesting article here breaking down the dynamics of Druuna. Frankly, I'm glad I only read the 'light' stuff in Heavy Metal, and not the hardcore material in the books. :S
serpueri is great art
