Stranger Things 3 is the new Netflix four-day streaming champion. The service said Monday that the third installment of the nostalgic horror series has been watched by 40.7 million household accounts since its Fourth of July launch and that 18.2 million already have binged the entire season:

.@Stranger_Things 3 is breaking Netflix records! 40.7 million household accounts have been watching the show since its July 4 global launch — more than any other film or series in its first four days. And 18.2 million have already finished the entire season. — Netflix US (@netflix) July 8, 2019

When Season 2 debuted in October 2017, Nielsen — which had said two weeks earlier that it would start measuring Netflix viewership on TVs — said the first episode averaged 15.8 million U.S. viewers and nearly 11 million in the demo viewing on the TV. The measurement service also said all of the nine new episodes averaged 4 million viewers and 3 million in the demo, saying “a significant viewing event occurred.”

Created by Matt and Ross Duffer, the eight-episode Season 3 of Stranger Things takes place during the summer of 1985 in Hawkins. School’s out, there’s a brand new mall in town and Mike and the guys are on the cusp of adulthood. Romance blossoms and complicates the group’s dynamic, and they’ll have to figure out how to grow up without growing apart. Meanwhile, as expected, a familiar and evolved danger looms. When the town’s threatened, the gang has to band together to survive.

The ensemble cast includes Millie Bobby Brown, Winona Ryder, David Harbour, Cary Elwes and Finn Wolfhard.
