Fan fiction is something I only started reading in the last few months. It’s actually Kind of fun.
I used to think fan fiction was derivative and people wrote them when they couldn’t think of their own characters. But I don’t think that’s true anymore.
It seems to me that people use them to explore story lines they wish had happened. Or scenes that the author left out. (I’ve imagined quite of a few those myself, but never actually wrote them down.) Sometimes I think people use them to explore what would happen if the character was different or if the world was different or both.
I think mostly people write to explore something they would like to see with the characters that didn’t happen. And, really, I have wished and pictured that same thing with TV shows/books/movies but just never wrote them down.
One of the most fascinating (to me, anyway) is this addition to the world someone came up with for Stargate: Atlantis, NCIS and I don’t even know how many others. The things that happen in Xanthe’s version couldn’t have happened in the show. Her additions couldn’t happen on any non-cable show and they are a stretch even on cable. But it is still pretty interesting. So, yeah.
