I've never seen the TV show, but everyone has been saying it's good. Which is why I figured I would check out the graphic novel. My assessment: the graphic novel is good. Artwork is nice, good pacing, interesting characters. A bit flat in some places, predictable in others, and I'd really like to see more of how society got to this state. Also, can a guy survive several weeks in a coma unsupervised? I doubt it.
