"Speaking with IGN about what’s next for the series, Stranger Things co-creator Matt Duffer indicated that the follow-up to the series would be better described as a “sequel” than a “second season.”
Duffer’s comments prompted some speculation that the series might not bring back its entire cast for whatever comes next, but producer Shawn Levy seemed to address those concerns in another, subsequent interview.
“The plan is to continue with this set of characters while introducing a few critical key new ones next season,” he told SlashFilm. “So I’ll just say that a lot of the big mysteries get answered at the end of Season 1, but we are very much kind of unearthing new problems and questions that merit future stories and future investigation in the most enjoyable way. So we are in love with our cast and our characters.”
“Things end up being resolved to some extent at the end of Season 1, but not entirely,” continued Levy. “And that’s why we’re so hopeful we get another few seasons to live with these people a little longer.”
