Stranger Things launched on Netflix in 2016 and became a pop culture phenomenon.

While the show’s ending after series five, there have been several key moments impacting the story.

Here’s a stroll down memory lane of Stranger Things, with moments from each series so far.

• Will’s disappearance: A central mystery in series one concerned the disappearance of Will Byers (Noah Schnapp). Everyone – from the police, his mother Joyce (Winona Ryder) and his loyal friends – were left on tenterhooks as to the boy’s whereabouts and what became of him. Mid-way through series one, Hawkins Police make a heartbreaking discovery after finding what is assumed to be Will’s body in a lake. Fortunately, it transpires this was faked.
• Dustin and Steve team up: Although they had nothing to do with each other in series one, series two saw Dustin (Gaten Matarazzo) and Steve (Joe Keery) become an unexpected team up. The polar opposite characters formed a surrogate brother-type dynamic which has endured throughout the show.
• Billy’s sacrifice: Billy Hargrove, played by Dacre Montgomery, made his debut in series two and was immediately established as an antagonist. In particular, he formed a rivalry with Steve Harrington. In series three, his villainous antics intensify after becoming the main host for the Mind Flayer. However, Eleven (Millie Bobby Brown) later breaks Billy free of the control by reminding him of happy memories with his mother. The bully sacrifices himself to save Eleven from the Mind Flayer – and dies in stepsister Max’s (Sadie Sink) arms.
• Eddie Munson’s death: Played by Joseph Quinn, the character Eddie Munson was a new addition in series four – and soon became a fan favourite. The President of the Hellfire Club, Steve feared he would replace him as Dustin’s older mentor figure. In the end, Eddie dies a heroic death – by sacrificing himself to save others from monsters known as “demobats.”
