The OA might have been the most mysterious and ambitious series ever seen on Netflix. But just as the genre-defying show added a new twist with a mindblowing cliffhanger, Netflix canceled The OA. The OA followed the formerly blind Prairie Johnson, who is telling her incredible story to a group of misfits in a nearby abandoned building after she arrives home, able to see and referring to herself as The OA, after she had been missing for seven years.
