If you’re like us, you probably finished the second season of Stranger Things, which may mean you’re looking for other ways to pass the time. Luckily, Netflix has released a trailer for a new, spooky, sinister, and dark original series called, well, Dark. According to the brief synopsis, “the disappearance of two kids in the German small-town of Winden opens abysses that turn the concept of time on its head. The question is not who has kidnapped the children . . . but when.” Sounds kind of like Stranger Things, Twin Peak, and something much more terrifying, all rolled into one. Watch the trailer above to get a taste of the madness, then rejoice: Dark arrives Dec. 1 on Netflix.
