I'm not quite sure what I made of this. It was a compelling read and once I started I couldn't stop, but at the same time it made very little impact on me. The concept and gender theme is fairly interesting, but the sci-fi conceit is lacking and seems solely to exist to pit the genders against each other and lacks any big pay off. Perhaps that's intended as part of the commentary on the nature of life, but it came off as feeling like the writers didn't really know what they were doing with it. Other reviewers seem to have sided with either the men or the women, however I found it hard to relate to any particular character, let alone a gender, and didn't much care what happened to anyone involved, which is probably part of the reason it fell a little flat. That said, some interesting dilemmas, situations, and moral problems arise, and it does keep you entertained throughout. As long as you aren't expecting to be blown away, the skilled artwork, film-like pacing, gore, humour, and unusual premise make for an enjoyable enough experience.
