Stranger Things season 4 may have introduced the perfect spinoff for the Netflix hit, and it's one that is neither a sci-fi show nor a horror series.

Duffer brothers say Stranger Things spin-off will 'be different than what anyone is expecting' (https://ew.com/tv/duffer-brothers-stranger-things-spinoff-different-than-anyone-is-expecting/)

In a new interview with Variety, series creators Matt and Ross Duffer teased a bit about what audiences might expect from their secretive Stranger Things spin-off (https://www.reddit.com/r/television/comments/vjxklb/duffer_brothers_say_stranger_things_spinoff_will/) project, which hasn't been formally announced or confirmed by Netflix.

Asked if they would wait until the fifth and final season of Stranger Things was complete to work on the yet-untitled project, they said they "probably" would. "There's a version of it developing in parallel [to season 5], but they would never shoot it parallel," Ross clarified. "I think actually we're going to start delving into that soon as we're winding down and finishing these visual effects, Matt and I are going to start getting into it."

Added Matt: "The reason we haven't done anything is just because you don't want to be doing it for the wrong reasons, and it was just like, 'Is this something I would want to make regardless of it being related to Stranger Things or not?' And definitely. Even if we took the Stranger Things title off of it, I'm so, so excited about it. But it is not… It's going to be different than what anyone is expecting, including Netflix."
