I love this type of fanfiction because the people that write them are analytically correct! There's nothing better than reading something with the correct use of "their", "there", and "they're". That aggravates me and whenever I read fanfictions about twilight (the fanfics are good, sometimes. Don't judge), or Vampire Academy, or Night World, or Supernatural, or The Hunger Games- they always have mispelled words, they tend to change the course of the story or things like that and I find when I read Pride and Prejudice fanfiction that it's not the case....I'm grateful for that. I love it <3
Not saying that there aren't good fanfictions for the books I mentioned below, but I just find that my best written stories (in diction) are from classics like Pride and Prejudice, Jane Eyre and Wuthering Heights (:
