MGM+ has a brand-new Stephen King horror adaptation arriving this summer, and its premise is similar to Eleven’s Stranger Things backstory. Inspired by Stephen King stories, ‘80s films, and classic horror and sci-fi media, Stranger Things combined these elements to become a massive phenomenon for Netflix, centering its story around a small town targeted by threats from the Upside Down, a realm with origins related to supernaturally gifted kids being experimented on by Hawkins Lab. In Stranger Things season 4, we finally got a glimpse at those kids’ upbringing in the lab, but much of the facility’s history remains mysterious.
