Netflix officially announced its renewal of the Stranger Things series, releasing a Season 4 teaser trailer in late September.

While a lot is unknown about the nature of the 4th season of the show, the trailer ends with the phrase, “We’re Not in Hawkins Anymore.” The official release date is still unknown.

Stranger Things is a Netflix original series following the lives of five children living in Hawkins, Indiana in the 1980s. Since the first season aired, the show has become one of the most popular on Netflix, with 26.4 million U.S. viewers watching the third season in the first four days of its premiere. Millie Bobby Brown, Finn Wolfhard, Gaten Matarazzo, Noah Schnapp, and Caleb McLaughlin are among the show’s original cast.

The third season introduced new characters, including Maya Hawke as Robin, and a larger focus was placed on Billy (Dacre Montgomery) as one of the central villains.

“My hope is that Billy comes back because he is a very dynamic character and he changed a lot over the course of the third season,” said Stranger Things fan and WHHS senior Maddy Gilman.

Season 4 is expected to premiere sometime in 2020 and, based on the overwhelming popularity of the first three seasons, will have high expectations to meet.
