I recently read a story by a beloved author - she's universally loved and appreciated in the fandom - and although I enjoyed the story (enjoyed it immensely in fact), I realized by the end that her Edward didn't resemble the Edward at all. (I won't disclose who but I will say it's not MOTU's author).
Sure - many, many Edwards in fanfiction aren't like Meyer's Edward. I know that and for the most part, I like that. BUT, a lot of them still retain something - even if it's just one trait - from the original canon.
This story had an Edward that, imho, seemed to be based largely on the author's personal experience (in an author interview, she actually mentioned that the story had many elements from personal experience). This is not criticism on the author, but just an observation by me and, based on the interview, somewhat of an admission by the author herself.
I've read 4 or 5 of her stories and thought the same about all of her Edward characterizations. As an Edward fan (he's the only reason I read fanfic) it left me feeling a bit disappointed. While reading the story, I kept shaking my head and muttering to myself, "That's not Edward. That's not him at all". I could name 100 canon personality traits and in my mind, none of them shined through. Same for her Bellas - which I adored - still frustrated me in the same way.
I still continue reading her stories because the writing is absolutely fabulous and the author is, by all accounts, lovely. I've never seen a single bad word said about her or her stories and because of her skill, the quality of her writing, and for her kindness in sharing her talent with the readers, I think the praise is well deserved.
Despite all that, I can't help but feel somewhat disappointed everytime I read her stories - kind of like I go into it to read a great Edward/Bella story and end up reading a great David/Sarah story with the names changed to E/B. I know that's my perception, and it probably sounds somewhat entitled, but even after I debated over posting this campfire, my curiosity won out...
I'm curious if other campers have felt the same about some stories and what your thoughts are after reading them? I'm not talking about controversial stories - like rape, taboo, or fetish fics - but rather thoughtful, inspired, engaging stories that you appreciate in and of themselves, but seem to take the fan out out of the term fan fiction. Do you come across stories like this? Do you appreciate them as imaginative interpretations of E&B or does it bother you in any way?
No need to name names of fics or authors and I'm honestly not looking to stir the pot. I'm genuinely interested about reader and author expectations when it comes to reading and writing fan fiction for the fans. Authors, do you feel any obligation to the readers (fans) about your characterizations given Meyer's framework? Or do you stay true to your own vision/plot bunny and why?
Please weigh in if you're inclined. I'd love to hear your thoughts.
