Netflix's supernatural hit "Stranger Things" debuted simultaneously on the streamer and in theaters on New Year's Day, giving the box office a much needed lift.

Warning: MAJOR SPOILERS ARE AHEAD for the series finale of Stranger Things, available streaming with a Netflix subscription now.

Stranger Things' star Gaten Matarazzo on the series finale, Eleven's fate, delivering that graduation speech and Steve and Dustin's friendship.

The final episode of the hit Netflix series debuted simultaneously Dec. 31 on the streamer and in 600 theaters before holding encore performances throughout New Year's Day.

Ross Duffer said Eleven's death, or disappearance, was integral to the story ending. Eleven represents childhood — and the finale is all about the kids of “Stranger Things” growing up.

If you believe internet rumors claiming the Stranger Things finale had “two hours” cut from its two-hour runtime, and have ignored actors and others saying that the claim is fake, the show’s creators have responded.

The 14-year-old newcomer to the Netflix mega-hit talks about Holly’s big final season arc and the “perfect” series finale: "When we finally read the script, everyone was in floods of tears."

Seasons 4 and 5 of Stranger Things consistently positioned Vecna as the villain, yet there were always complexities to his story. There was little getting around the fact that he'd committed heinous acts (he wiped out all the Hawkins Lab kids, after all), but questions arose early on about the extent to which he was in control.
