Stranger Things is coming to an end after season 5, meaning that fans have to search for a replacement series, and, thankfully, Stephen King is developing an adaptation of a 2019 book that shares similarities with the Netflix show. The science fiction horror drama television series, created by the Duffer Brothers, debuted in 2016 and instantly took the world by storm. After four triumphant seasons, Stranger Things is sadly set to end with its fifth season, which will consist of eight episodes and likely premiere in late 2025 or early 2026.
