Stranger Things is an American science fiction horror drama series created by the Duffer Brothers (Matt and Ross Duffer) that premiered on Netflix on July 15, 2016. Set in the fictional town of Hawkins, Indiana, in the early 1980s, the series follows a group of young friends, their families, and local authorities as they confront supernatural events linked to a terrifying alternate dimension known as the Upside Down. The show's premise draws heavily from the science fiction and horror films of the era, particularly the work of Steven Spielberg, John Carpenter, and Stephen King.

The ensemble cast includes Millie Bobby Brown as Eleven, a girl with telekinetic abilities who escapes from a secretive government laboratory, alongside Winona Ryder as Joyce Byers, David Harbour as Chief Jim Hopper, and young leads Finn Wolfhard, Gaten Matarazzo, Caleb McLaughlin, Noah Schnapp, Sadie Sink, and Natalia Dyer. The series was shot in and around Atlanta, Georgia, with production design crafted to authentically replicate the visual look of the 1980s, and its synthesizer-driven soundtrack has become one of its most celebrated elements.

Stranger Things became a cultural phenomenon almost immediately upon release, earning Netflix its first Emmy Award nominations for a drama series. Over its run of five seasons the show consistently broke streaming records and revived classic 1980s music for younger audiences. Season 4's use of Kate Bush's 1985 song "Running Up That Hill" caused it to re-enter the global charts at number one nearly four decades after its original release — one of the most remarkable music revivals in pop history.
