The OA is an American mystery drama Netflix series with science fiction, supernatural, and fantasy elements, which debuted on Netflix on December 16, 2016. Created and executive produced by Brit Marling and Zal Batmanglij, the series is their third collaboration. The series consists of eight episodes, all directed by Batmanglij, and is produced by Plan B Entertainment and Anonymous Content. In the series, Marling stars as a young woman named Prairie Johnson who resurfaces after having been missing for seven years. Prairie now calls herself "The OA" and can see, despite having been blind before her disappearance.
The OA received generally favorable critical reception. The series' directing, visuals and acting were often singled out. Reviews also ranged from highly positive to negative, with several reviewers drawing both favorable and unfavorable comparisons with Stranger Things, another science fiction series that debuted on Netflix earlier in the year.
On February 8, 2017, Netflix renewed the series for a second season, dubbed "Part II."
