One thing that gets under my skin is plot holes in my story. But I've done some research and it turns out that plot holes are even in critically-acclaimed stories like Lord of the Rings, Harry Potter, and Yu-Gi-Oh. I would like to think that my story is consistent enough to where there are no obvious plot holes, but I can't help but think that if even the greatest stories have them, maybe having plot holes is just a part of the human condition of being a writer? That said, there are some plot holes that are simply unforgivable. What measures do you take to ensure that your story is consistent all the way through?
