Is the author ever “wrong” about his own work? Not when it comes to events and plot points.
Rex Stout, creator of Nero Wolfe, was brilliant at creating a world and an atmosphere, but his plots were frequently weak. It often appeared to me that he decided at the last minute who the killer was, without having given the reader any clues. Nonetheless, it’s HIS story. If he “proves” that bartender Larry Schwartz was the killer, then Larry Schwartz is the killer. Stout can’t be 'wrong" about that. We readers may argue "That was a pretty weak solution to the mystery, and we may be correct about that. But the story is the story, and whatever solution Stout wrote down is the “right” ending.
It just so happens that the “right” ending may not be satisfying.
A sloppy writer may contradict himself here and there, but he/she gets to detrmine the details of his/her story. IF Arthur Conan Doyle mentions that Inspector Lestrade is bald (I’m making that up), then Lestrade IS bald. IF John Updike mentions that Harry “Rabbit” Angstrom is left-handed (again, I’m making that up), then Rabbit IS left-handed. IF P.G. Wodehouse says that Bertie Wooster’s belly button is an “outie,” then it is. We don’t get to tell the author he/she is wrong about the facts in a story. And since*** Blade Runner ***is Ridley Scott’s movie, he gets to decide if Deckard is a replicant.
We CAN tell an author, “That fact you told us doesn’t seem to fit with other things you’ve told us,” or “That action you showed the protagonist doing seems totally contrary to everything you’d previously told us about him” or “You didn’t give us nearly enough evidence of that.” But that’s beside the point. We can tell an artist, “That’s a bad ending” but we can’t tell him, “That’s not how the story really ended.”
Beyond that, suppose you read a poem or story, and it gives you an amazing insight you’d never had before. Or, perhaps you glean a message in the story that deeply touches or inspires you. Suppose you then meet the author and say, “You know, your work really helped me to realize SUCH-AND-SUCH.”
If the author replies, “Well, I wasn’t thinking that at all, and I never intentionally put such a message in my work,” is the author WRONG?
No… but unless you’ve come up with a totally insane, warped interpretation, I think the author should be pleasaed. The athor probably should listen to your insight and say, “Hmmm… that’s interesting. That isn’t what I was attempting to say, but I’m pleased my work stimulated your thinking and helped inspire you. That means the work was a success.”
To use one example, I’m almost certain Robert Frost’s “Stopping By Woods on a Snowy Evening” had nothing to do with suicide. But some depressed people have undoubtedly read that poem and found the strength to go on living. I don’t believe Frost would snarl, “You idiiots, that’s not what the poem was about at all!” He’s have been pleased that the poem was alive and multi-dimensional enough to touch many people on different levels.
