It is an impressive work about the difficulty of founding life in logic. To illustrate let me explain it in terms of why a librarian would be frustrated by the book itself, in the sense of how to classify it. It is a book but also a comic. A work of fiction made up of fact. Metafictional in that it tells the story of the story of the creation of the story about a man who tells a story which is a story (to say the least). Is it history? Certainly. Biography? Also yes. Literature? I don't see why not. Math? Y. Philosophy? Yes. Psychology? Perhaps. A romance? Sure. Mystery? OK. Is it for adults/teens? Should there be tags for pacifism, isolationism, Nazism, free love, computers, and Greek tragedies? A yes to all... and none. The list of possibilities and difficulties goes on, and on, and on, and on some more. And this might be part of the problem as for all it's impressiveness the work gets sidetracked by itself. No wonder it took two people to write and two additional people to draw it.
