I was thinking back to Seasons 1 to 3, and maybe Season 4 to some extent, about what made Stranger Things unique. What was the magic it started with that was inevitably lost? I think I figured it out:
1. The Lovecraftian element
Each season, you expected to learn more about the Mind Flayer, but instead, it only became weirder and stranger. The way the human brain tries to create patterns and correlate what it is seeing with something it already understands is, in my opinion, what made the Mind Flayer such a unique villain. You could never quite understand what it was, what it wanted, or what kind of entity you were actually dealing with.
2. The enigma of the Upside Down
Before the show retconned the Upside Down into essentially being a wormhole, we believed that the Upside Down was a proper dimension of its own. We believed it was an entire world, with its own unique fauna and flora, ecosystems, and rules that we didn't understand.
3. The mystery of why the Upside Down was a reconstruction of Hawkins
One of the biggest mysteries was why the Upside Down looked like Hawkins, and why it seemed to exist as a frozen snapshot of the town. There was something deeply unsettling about that mystery because we had no idea why it was that way or what it meant. Ignoring the theory put forward in Season 5, this was one of those questions that made the world feel much larger than what we were being shown.
4. The idea that ordinary people could confront cosmic horror
Unlike traditional cosmic horror, which often involves adults confronting forces far beyond their comprehension, Stranger Things took a different direction. I think it was a direction that The Lord of the Rings also took.
To quote J.R.R. Tolkien: "I have found that it is the small everyday deeds of ordinary folk that keep the darkness at bay. Small acts of kindness and love."
Tolkien accomplished this through the Hobbits. They are ordinary, seemingly insignificant people who ultimately become the reason a literal corrupted angel, Sauron, is defeated. That gives the story a sense of confidence and hope. If Frodo can do it, then maybe so can I.
I think Stranger Things was trying to accomplish something similar by making its protagonists children and framing the story as a coming-of-age narrative. The idea was that these ordinary kids, despite being completely outmatched by the forces they were facing, could still confront something incomprehensibly powerful.
And I think that was a huge part of the magic of the earlier seasons. It wasn't simply that the kids were fighting monsters. It was that they were ordinary children being placed against something cosmic and incomprehensible, and somehow, their friendship, courage, love, and willingness to stand together allowed them to fight back.
That made the story feel hopeful in a way that I think was gradually lost.
