Surprised to see no one talking about it. This is a new show by The Duffer Brothers (who directed an indie thriller Hidden, and wrote a couple of episodes of the first season of Wayward Pines) on Netflix. It starts Winona Ryder, David Harbour (who's everywhere these days ^^), Matthew Modine and a bunch of wonderful kid actors y'all be hearing about soon enough.
It's set in the 80's, and basically, it's a mashup of everything you love if you're into that stuff, meaning it has elements of sci-fi mode Spielberg, ala E.T, Super 8, Stephen King, you got a group of kids, one of them disappearing, a weird girl in a hospital gown that runs into them and is special, you got the kids on bikes, you got the heavy sci-fi element, the mystery element, the supernatural element, the great soundtrack with a heavy synth score, wonderful cinematography and you get a not to miss show.
Tim Ives (Mr Robot pilot) shot the hell out of it, it's basically a series that looks like it cost much more than it probably did, extremely high production values, fantastic cinematography, shot on Red Dragon and Leica lenses (confirmed to me by Tim Ives).
Binge it, embrace it, love it.
