So, writing the story the writer wants to tell is "screwing over the fans"?!
Interesting, how many good stories would have been told or written throughout the history of mankind, if all the authors would have been forced to listen to their fans and follow their demands?
I'd estimate 0.
Just a few well known and popular examples here:
Shakespeare would have been forced by the crowd to keep Julia alive and marry her to the guy of her parents choice. And he probably would have killed himself of frustration of not being able to write anything he actually enjoyed to write.
Tara would be still alive and not a lesbian, Spike would have been dusted permanently in the first season in the Buffy the Vampire Slayer. And it probably never would have managed to get to the second season, so we wouldn't even know the Tara character.
Smaug would have died of pneumonia before the Thorin gang reached the mountain, Sauron and the ringwraiths would have been eliminated by shit knows what before the hobbits reached Bree.
All the stories would be happy-happy all the time and all the characters would be "teletubbies".
Most of the human kind would have died of brain aneurism that they got from utter boredom.
No, a writer should
never listen to his fans when he knows what he wants to write about. He can only listen to them about the things he's not sure about and that would not conflict in any way with the story he wants to write.
