Fanfiction helped save Star Trek! Women wrote more stories because there was so much missing when the show was canceled. Fanfiction kept the series alive for the fans and helped them build a community together.
Give it a try!
Now how would you change the story? You don't have to make the commitment to actually writing out this new story arc. But think about it.
Did a character you love die? How would you save them? How would that change the story? How would the other characters be affected?
Insert yourself into the story. Make yourself a character. Who would you be? What part would you contribute?
Have fun playing in fanfic!
