“Stranger Things” (Season 1 on Netflix)
There’s no reason to not have watched this ’80s horror-adventure pastiche, unless you’ve been in the upside-down. (You’ll get the reference when you watch.) It’s only eight episodes, and “Stranger Things” has the best kid cast we’ve seen in years — plus Winona Ryder.

“Narcos” (Season 1 on Netflix)
Most people know the Pablo Escobar story, but the 10-episode first season on Netflix is unmissable. Wagner Moura scored a Golden Globe for his performance as Escobar, and for those missing the Red Viper from “Game of Thrones,” Pedro Pascal is here for your viewing pleasure.
