People discussing ‘unhinged’ fanfiction always seem to talk about dark!fic or explicit stuff, as opposed to the truly unhinged stuff like the fic author zapping all their favs from a story onto a set, assigning them roles, and forcing them to act out popular movies. Because, let me tell you, I read a fic like that with the original Yugioh cast acting out Disney’s Aladdin approximately fifteen years ago, and it is to this day one of the one of the most unhinged pieces of media I’ve ever consumed.
