The creators of the hit Netflix drama Stranger Things have revealed that they envisage the show ending after four seasons.

Brothers Ross and Matt Duffer created the series, which returns for its second outing on October 27, and they already have an endgame in sight for the show.

"We're thinking it will be a four-season thing and then out," Ross told New York magazine.

The first season focused on a band of friends trying to get a member of their group back after he disappeared into a mysterious alternate reality during which they forged a bond with hero Eleven, played by Millie Bobby Brown.

"We just have to keep adjusting the story," Matt Duffer said. "Though I don't know if we can justify something bad happening to them once a year."

Despite her sacrifice at the end of the first season, Eleven will return for series two, which will premiere on the streaming service on October 27.
