All good things must come to an end—even Stranger Things. The show’s creators, Matt and Ross Duffer, announced the news with a bittersweet letter to fans citing that the hit Netflix sci-fi thriller, which first arrived in the summer of 2016, will conclude with its fifth season, which has no release date yet. It’s too early to say. In the meantime, though, we can look forward to the two-part season 4, which arrives this summer. The first volume premieres on May 27 while the second comes July 1.
