“The OA” is ending after two seasons on Netflix .

The series premiered in December 2016 with eight “chapters” that veered pretty far from traditional TV storytelling — the opening credits didn’t roll until nearly the end of the first episode, and episode length varied from 30 minutes to one hour and 10 minutes. Then, after that first season, fans had to wait two-plus years for the show to return in March 2019.
