In my opinion its extremely overrated. I'm not sure what it was that didn't click with me but i just found it all a bit silly. I never thought that any of the character reacted like real people in that situation.
Also my most favorite comic series. The moment I turned the page and was greeted with the destruction from the event, I was hooked. To this day it's still one of the best anything at depicting women as real characters and not as dressing.
Yeah that was pretty dumb, I agree. Also I never really liked that
the explanation for why all the men died was never really explained. It's like, he had this really neat premise for a setting, but knew that it didn't quite make any plausible sense, so he decided to never bother explaining it... xD
