I have thought recently about some of the principles that I believe in when it comes to fiction stories and genre. I am not speaking about genre in the more traditional sense. When I go to Amazon, I realize that if I go to the Fantasy section, then I will get results that reflect books having to do with magic, mythical creatures, swords, and the like. I am speaking in this post more to the general idea of a fantasy. A fantasy is something created in one’s imagination. Something that has not actually happened. See how that fits into fiction? Fiction is a story that never actually happened, created from someone’s imagination.
Of course the next question you have, after accepting that premise, is, “So what?” I hear you. I notice many writers and readers get caught up in the “reality ” of stories. In science fiction, I have seen some argue about whether or not space travel in X manner (notice I dodged the argument by using a variable instead of mentioning a specific method.) Some people only want to write or read those science fiction stories that reflect realistic technology. My take on it is that it is called science FICTION for a reason . If it was real, it would be called a science textbook.
What I see many authors gloss over these days, however, is what I call internal consistency. This applies to everything that is created within the story. It applies in many ways, and it requires the writer to be somewhat cerebral. Before he became delusional and arrogant, M. Night Shyamalan created the Sixth Sense. He created certain rules that he followed throughout the movie. For example, anything the dead interacted with in the physical world was red. After the surprising ending, one could go back and see all of these rules in place throughout the movie. I remember seeing an interview with him, where he described going through scenes and looking for discrepancies in the color scheme, sometimes finding a problem right as they were starting to shoot.
This, to me, is internal consistency, and is very important to me in the stories that I enjoy. I want stories to be consistent with the rules created in that world. If this is a story where the ghosts cannot speak to the living, then I do not want to catch a ghost talking to a living person, unless there is a development in the story that accounts for this. I don’t want to see a character that acts wildly outside of their established personality. Internal consistency, in my estimation, is critical in any fiction story. As far as whether or not certain elements are realistic? It is all fantasy, which is not real by definition.
