'Stranger Things' season 2 spoilers: More of the '80s and Barb Holland next season

After the critically acclaimed pilot season of Netlix's supernatural-horror television series "Stranger Things," the show has been gearing up for another season of thrills and mystery.
There are many things that fans love about the show but perhaps its best feature is its references to '80s culture, particularly its homage to films made during that decade.
The Duffer brothers, Matt and Ross, recently revealed to IGN that season 2 will be set in 1984, a year after the first season.
In an interview with IGN, the Duffer brothers emphasized that 1984 was a great year for pop culture and the film industry. The brothers said they will once again be incorporating the magic of '80s films, including "Indiana Jones." They admitted that they love "Temple of Doom" and they like how it gets darker and weirder from "Raiders." They added that they don't intend to traumatize the children next season but they do intend to make the plot darker and weirder.
Ross said they're treating season 2 as a sequel for season 1. Since Will Bryer's (Noah Schnapp) disappearance has been resolved, the forthcoming season will be introducing new conflicts and tension. The goal is for the characters to solve this conflict before the end.
Although new issues will arise, Matt shared with IGN that they will be revisiting one unresolved and seemingly forgotten mystery in season 1 — Barb Holland (Shannon Purser).
When Eleven (Millie Bobby Brown) attempted to find Barb and Will in the alternate dimension or the "upside down," El found out that Barb had died. Since the government made the entire town believe that Barb had deliberately left town, her disappearance wasn't given any justice. In season 2, the showrunners will be exploring "the repercussions of everything that happened" in the preceding season.
More importantly, Matt said that season 2 will not be the last. He admitted that they're still trying to figure out how long they need to get to the ending but they definitely find it difficult to stretch the series for six or seven seasons.
As of now, neither Netflix nor the creators have announced the premiere date for season 2 of "Stranger Things."
