The conclusion of Stranger Things left many enthusiasts so reluctant to bid farewell that they crafted elaborate theories regarding a hidden bonus chapter, fueled by perceived narrative gaps in the finale. However, the newly released documentary, One Last Adventure: The Making of Stranger Things 5, offers a far more practical explanation for these creative choices: the Duffer Brothers began principal photography on the feature-length finale without a finalized script.
[Note: This breakdown contains significant spoilers for the final season of Stranger Things.]Reflecting on a decade spent in Hawkins, the Duffers admit early in the film that the pressure to deliver a poignant resolution was immense. Netflix and the production team were relentless in their pursuit of the final teleplay, which the brothers describe as their most daunting writing challenge to date. Remarkably, even at the midway point of the 237-day production cycle for season 5, the script remained incomplete. This led to filming several key sequences—such as Holly Wheeler’s (Nell Fisher) escape alongside the other young captives of Vecna—long before the narrative path was fully paved.
Beyond the logistical hurdles, One Last Adventure reveals several fascinating insights into the series’ final act:
The Creative Struggle Over Eleven’s Destiny

The showrunners particularly agonized over the fate of Eleven (Millie Bobby Brown). They wavered on whether she should make the ultimate sacrifice by remaining trapped in the Abyss as the gate sealed. Ultimately, they decided that Eleven—as the embodiment of the story’s “magic”—had to leave Hawkins behind. This bittersweet departure, coupled with the Party storing their Dungeons & Dragons gear in Mike’s basement, was designed to mirror the end of childhood—much like the closing of the door to Narnia. While the Duffers suggest other children may one day find the magical threshold, the journey has definitively ended for our core protagonists.

The documentary provides a fly-on-the-wall perspective of the writers’ room debating the final confrontation within the Abyss. Matt Duffer advocated for the Mind Flayer’s visual dominance, with early concepts involving a battle literally inside the beast. Character-specific requests also emerged; Finn Wolfhard lobbied for Mike to carry a firearm, a request the Duffers playfully modified by having Mike receive a flare gun from Nancy. Discussions also swirled around “monster fatigue.” While some writers pushed for a crowded battlefield of Demogorgons, others, like Kate Trefry, feared diluting the impact after the midseason’s creature-heavy action.
Ultimately, Trefry’s vision of a desolate Abyss prevailed. The Duffers also confess to their struggles with blue-screen environments, which were utilized to craft the surreal, amber-hued desert of the void. This stood in stark contrast to the tangible sets used for the episode “Sorcerer,” which featured a massive practical backlot and the 130-foot “pain tree” structure that took months to construct.
Further Tidbits from the Production Archives

Alongside emotional footage of the cast confronting the final script, the documentary reveals several hidden gems:
- In early conceptual sketches, the Abyss was labeled the “Shadowfell”—a direct nod to the D&D Plane of Shadows and the home of the vampire Strahd Von Zarovich, the antagonist of the kids’ final campaign.
- Vecna’s aesthetic was far from certain; the VFX department cycled through 100 iterations, ranging from spiked monstrosities to insect-like creatures, before settling on the iconic vine-covered design.
- The Duffers’ own mother was devastated by the death of Bob Newby (Sean Astin) in season 2. While the brothers joked at the table read about “killing more of you off,” they ultimately spared many characters to preserve the show’s core sense of wonder and camaraderie.
