A newly released behind-the-scenes documentary on Stranger Things Season 5 has sparked fresh conversation among fans, after revealing just how uncertain the show's ending once was. Far from having a single fixed finale in mind, creators Matt and Ross Duffer explored multiple directions for how the story of Hawkins and especially Eleven could conclude before finally settling on what made it to screen. The documentary pulls viewers inside the writers' room during the final stretch of production, where whiteboards, index cards and late-night debates became the norm.
