The second season of Netflix's hit series "Stranger Things" hasn't even debuted yet, but that hasn't stopped its creators from thinking about what lies ahead for the show -- and just how long it could run on the streaming service.

In an interview with Entertainment Weekly, the Duffers -- a.k.a. brothers and co-creators Ross and Matt Duffer -- chatted about the future of "Stranger Things," both in season two and beyond. And according to the duo, they have thought about how many seasons of the show they'd ultimately like to make, telling EW that the sweet spot they're currently considering is four or five.

Still, the brothers stress that they don't want to wear out their TV welcome, and will wrap the story when they feel it's time. They'll reassess their plan from season to season, they said.

"Everything changes as we move forward so we'll see," Ross Duffer told EW.

"I want it to have a really finite ending," added Matt Duffer. "I don't want it to be one of those shows that runs out of gas and they lose it because they're losing interest. You wanna end when you're on top."

Fans shouldn't worry about the show ending anytime soon, though: The Duffers also told EW that season two definitely sets things in motion for future seasons.

"Stranger Things" returns to Netflix for its sophomore outing sometime around Halloween.
