So what is the difference? What makes one so boring you can't pick it up and the other one so exciting you are sorry when it is over? It is the story telling. Good story telling can overcome genre preferences, author biases, and even typos. For example, while I was working on a story on my iPad, I printed up a copy to share with my friends. Thanks to the app and auto correct, there were typos and missing words all over the place; however, because my friends were into the story, the only person to notice these errors was me. My friends were into the story. They wanted to know how it would end. They wanted to know about certain characters. They did not care that in was a "hot mess."
Books, movies, TV shows, and the lot, succeed or fail based not on the special effects (though some may argue that), the stars involved, or even the author himself, but rather how well the story is told. Sometimes, if the story is bad enough, it actually captures our attention on another level, perhaps the freak show level (or recent times, Sharknado comes to mind). Yet, for us as human beings, we need the story to entertain us and for us as writers, we need to perfect the art of story telling, to keep the interest of those we wish to entertain. So here's to perfecting our craft!
