Season 5 of Stranger Things will feature the final battle for Hawkins, while Season 4 is left on a huge cliffhanger. 

When Season 5 was first announced, the Duffer Brothers said in a statement that the "entire story" had been planned seven years ago, and that the fifth outing would conclude that plan.

He confirmed that the ending still conforms to the "rough outline" he created, but that it has become "more interesting and exciting than Ross originally envisioned".

He said: "We know what the ending is. That could change, but I still think it's less and less likely, because it's one of those things.

What always feels right and always feels right. And it seems inevitable. Then when you think about it a bit, you say, oh yeah, that's exactly how it was supposed to be.

I accept it. I can tell you what I was doing — no one, including me, was crying when the Duffers introduced the Season 5 storyline.

For Stranger Things Day last year, the Duffer brothers released the first line of the script to give us an idea of ​​how the show will begin. Buckle up, it's a horror show.

Of course, after the scene unfolded, the internet abounded with theories as to which song the script was referencing.
