"A deeply enjoyable man vs world story"
Too many Man vs. World stories rely on characters who lack flaws. Characters who would be perfectly great at everything if the world would stop keeping them down.
Alan, our lead in Hologram, is a deeply flawed man. He is jealous and fearful, watching his life and dreams fade away and out of his grasp.
Alan wants to play by the rules, all the rules, but the rules refuse to stand still. He wants to do the right thing, but the right thing is never clear. He makes good decisions that go bad and bad decisions that work out just fine.
He is a sympathetic man, immanently relatable. This is good, because the story itself, when considered from afar, is quite boring. The journey of an interesting character struggling in an interesting location is enough for Dave Eggers to have a winner.
