Facts About Stranger Things
The second season was originally totally different
In the case that Stranger Things wasn’t picked up for a second season, the Duffers created a complete story in the first season. So when the show became a hit and Netflix extended the contract it wasn’t their first choice to continue the story and one of the ideas they had was to make Stranger Things into an anthology series.
Another one of their ideas was to do a sequel that was set around a decade later in the 90s.
