Would you like to know the best way to ruin the aesthetic integrity of a book? It's pretty easy. Just pick your favorite literary obsession- The Lord of the Rings, Finnegan's Wake, The Trial, The Iliad, The New Testament, hell, even the Twilight series- then find a fan group (online or off) and start picking away at the narrative until there's nothing left but bone, break the bone and suck the marrow. Don't spend too much time thinking about the fact that the story (which you claim to love) was alive when you started gnawing away at its flesh.
Now I'm not saying that there's nothing to be found beneath the painted surface of an author's work, and I'm not denying that many writers welcome, even crave, a closer reading of the pages they took so much effort to craft. But a writer also understands (or ought to understand) that the act of creating a story for others often involves ruining much of its beauty within themselves. I can't imagine that any author who truly loves the work they've given life to would wish to see it pulled to pieces upon the altar of fandom, that "deplorable cultus" as Tolkien so aptly put it, and I can't see why some readers can't be satisfied with the pulse and rhythm of a story's heart, that they have to dig it out and eat it, too.
