The Duffer brothers' next sci-fi show after Stranger Things is only months away from its debut, which looks as though it could well repeat much of what made Stranger Things itself so successful. It's safe to say that Stranger Things is one of the most successful Netflix shows of all time, with the series' final two seasons being the third and fourth most-watched seasons of any show ever on the platform, beaten only by Wednesday season 1 and Adolescence.
