The biggest TV show in history has finally addressed its most burning questions, answering mysteries that have lingered for nearly a decade. The Duffer Brothers had warned that the Stranger Things series finale would defy expectations, and they were right. The finale revealed the dark truth about The Upside Down, the role of the Mind Flare, and VCNA's twisted backstory, expanding the story beyond what was anticipated.
The Mind Flare, which hasn't appeared in its full form since the end of season 3, has always been central to the plot. Henry encountered the Mind Flare in The Upside Down and merged with it, thereby extending his influence over other beings and possessing them. This was unclear until now. The spiderlike creature seen in season 3 wasn't the Mind Flare’s true form but rather dark particles shaped by Henry's imagination. The Mind Flare is revealed to be ancient, possibly as old as the universe, waiting for a vessel like Henry to manifest its intentions.
The finale also focused on characters like Eleven, who along with her siblings, received their powers from Henry, indicating they were forever connected to him. This connection created a perplexing threat to humanity since Henry's essence existed within them. The final revelation that the Mind Flare had been waiting and building in the abyss suggests its presence is far from over.
Questions were raised about characters like Ted Wheeler and the seemingly inevitable fate of characters like Will. Yet, several mysteries were left unanswered, paving the way for future explorations possibly involving the next generation in Hawkins.
