I like fanfiction. I like reading it, and I’ve come to enjoy writing it.
That being said, I’ve come to the opinion that all fanfiction, no matter the fandom or author or intent, is AU–or Alternate Universe.
You want to change a death to life? AU.
You want to change love interests? AU.
You want to change entire storylines? Very AU.
Complaining that something in fanfiction is not like it was “in the show” or “in the book” is just useless and counterproductive. It’s supposed to be different. If it wasn’t, then we’d all be in copyright court for infringing all over the place.
Also–if you don’t like non-canon AU, then seriously don’t read my stuff.
