According to Vince Auletti in the Village Voice
"What makes "A Storybook Life" so enthralling isn't diCorcia's proven skill at crafting a convincing fiction, it's his ability to invest the whole nearly indigestible enterprise with feeling: longing, confusion, regret, tenderness, dismay, love, and, above all, a kind of bruised optimism. It's the accumulated weight of this emotion-however muffled, disguised, or denied-that gives the work its power as a piece. DiCorcia is no sentimentalist; he's far too smart and too subtle. He's not spilling his guts, he's constructing a riddle that even he doesn't know the answer to. All the more surprising that, in the end, he's also created a piece that doesn't seem to be just about his life, but ours."
I could not have said it better myself.
