Netflix is returning to the Upside Down.

The streaming giant has renewed the Duffer brothers' breakout hit “Stranger Things” for a third season. A return date has not yet been determined for the supernatural drama about the happenings brimming beneath the surface of a small American town.

While Netflix — like fellow streamers Amazon and Hulu — does not release viewership information, measurement leader Nielsen cited an audience of 15.8 million viewers who watched the season two premiere within three days of its launch, and nearly 11 million of them were among the key adults 18-49 demographic. Nielsen also found that 361,000 Netflix subscribers streamed the entire nine-episode second season within 24 hours of its debut. The second season also was crowned the most popular show in the country, according to data company Parrot Analytics, says The Hollywood Reporter.

Even without ratings from Netflix, “Stranger Things” ranks as the service's biggest franchise. The series, which collected 18 Emmy nominations (taking home five), is pulling Netflix into a new business with a series of licensing deals for clothing, posters, toys and collectibles.

While the cast is signed for six years, talent reps say a renegotiation will happen in early 2018 especially considering the massive success of the show.

After launching with immediate impact in July 2016, “Stranger Things” released its nine-episode second season in October, days before Halloween. Set in a small town called Hawkins, Indiana, in the middle of the 1980s, “Stranger Things” focuses on a crew of kids who call themselves 'The Party', including leader Mike Wheeler (Finn Wolfhard), the frequently endangered Will Byers (Noah Schnapp), straight-shooting Lucas Sinclair (Caleb McLaughlin) and eternally upbeat Dustin Henderson (Gaten Matarazzo). In the first season, Will goes missing, abducted into the shadowy Upside Down. He's saved thanks to the arrival of Eleven (Mille Bobby Brown), a young girl with telekinetic powers. Season two sees Eleven enhancing her abilities while the threats of the Upside Down resurface and expand. Unlike the first season, season two ends in such a way that there's very little clear direction about the future of the series — exactly the way the Stranger Things creators envisioned it.
