Once you fall in love with a movie, book or TV series, you are loyal like an old dog. You take fanfiction quite seriously and use it as a substitute after the canon runs out.

You are probably a walking dictionary of your favourite fandom and you are picky about what you write and read. The closer to the "real thing" fanfiction is, the more you like it.

You would rather explore a character in all depth, see new sides and learn more about them than create new characters or mix up the situations they are in.
