Want more 'Stranger Things'? 'The OA' is Netflix's gift to you

The promising new eight-episode series also has a mysterious disappearance at its heart, though we didn't spot any Eggos in the preview.

Is there a "Stranger Things"-shaped hole in your heart? You could eat your feelings with Eggos, or you could tune in to Netflix's new original mystery series, "The OA," which launches globally on Friday.

Netflix surprised many by dropping the trailer on Monday with little or no publicity. But the network has high praise for its eight-episode show, calling it "a powerful, mind-bending tale about identity, human connection and the borders between life and death."

Big words, but the preview backs them up with an intriguing premise and some promising scenes.

From what we can gather, Prairie Johnson disappeared seven years ago and has somehow resurfaced. But when she vanished, she was blind, and now, she can see. The trailer also includes "Stranger Things"-like elements, including strange markings on Johnson, a car careening off a trestle, an ominous blood (we think?) trickle, and a sense of a supernatural universe just beyond our sight.

"The biggest mistake I made was believing that if I cast a beautiful net, I'd catch only beautiful things," says the returned Johnson (Brit Marling, who also created the show with Zal Batmanglij). We don't know what she means, and we also don't know what "OA" stands for, but for now, we're going with it.

The cast also includes Jason Isaacs and Phyllis Smith, and Johnson's father is played by Scott Wilson, who many will remember as the gentle veterinarian Hershel Greene in "The Walking Dead." That last bit of casting led one YouTube commenter to note, "Looks like Eleven has been adopted by Herschel."
