The structure of showing the same man's death at different points in his life is an interesting one. It's enough to make an engaging and possibly thought-provoking book.
And in some cases, the right people can run with that concept and turn it into a brilliantly profound work.
The art, first off, is great. It evokes emotion and life, and it's just plain nice to look at. The story, the thoughts on life and death and stories themselves, that's what makes this graphic novel a brilliant piece of fiction. It's powerful, aided by pitch-perfect writing. It's memorable and beautiful and is as hopeful as it is melancholy. I loved this book.
