Documentary reveals Stranger Things 5 writing process and fan controversies

Netflix released the behind-the-scenes documentary One Last Adventure: The Making of Stranger Things 5 on Jan. 12th, 2026, Movieweb reported. The film showed the Duffer Brothers writing Season 5 in Google Docs, included Matt Duffer joking, "We probably should have killed some of you off.

Millie was right," and prompted viewers to note Reddit and ChatGPT tabs open on the creators' computers — though it is unclear whether AI was used. The Duffers said they "went into production without having a finished script for the finale. That was scary because we wanted to get it right.

It was the most important script of the season," adding, "How do you meet those expectations but surprise the audience still?" The documentary also highlights Maya Hawke pointing out that Robin and Vickie's relationship is not explained to other characters, writer Paul Dichter saying, "There have to be some monsters in the Abyss," and the Duffers' comment about viewer "demo fatigue." The report referenced a reportedly $400–$480 million budget, according to Puck News (via Forbes).
