A new documentary, "One Last Adventure: The Making of Stranger Things 5," released on January 12/13, offers a behind-the-scenes look at the final season's production. The film reveals the Duffer Brothers began shooting without a complete script, facing immense pressure to deliver a satisfying conclusion. While intended as a farewell, the documentary has sparked mixed reactions, with some fans expressing disappointment with the ending and others speculating about AI's potential involvement in writing, a point amplified by a brief laptop screen in the film.
