It’s a sad day for fans of The OA hoping the series might return for a third season.

According to Variety, Netflix has officially pulled the plug on mystery thriller The OA after just two seasons.

Shortly after news of the cancellation broke, The OA co-creator Brit Marling (who also stars in the series as the titular character) took to Instagram to share the news with fans far and wide.

Marling shared a long letter with fans via the photo sharing platform in which she touched on her own passion for the world of sci-fi storytelling.

“We feel profound gratitude to Netflix and the people we have worked with there for making it possible to make Part 1 and Part II. We feel proud of those 16 uncompromised hours,” wrote Marling.

Addressing fans of The OA specifically, Marling continued: “In large part, millions upon millions of you have given us this sense of pride by watching— with the comments you’ve left, the art you’ve made, the Reddit theories you’ve sown, the movements you’ve performed in public squares, bedrooms, nightclubs and backyards all over the world.”

Said Netflix’s vice president of original content: “We are incredibly proud of the 16 mesmerizing chapters of The OA and are grateful to Brit and Zal for sharing their audacious vision and for realizing it through their incredible artistry. We look forward to working with them again in the future, in this and perhaps many other dimensions.”

First premiering in December 2016, The OA was co-created by Marling and Zal Batmanglij, and centered on a blind woman (Marling) who disappears, only to return seven years later with the ability to see again.

Once back in her hometown, she sets out to recruit a team of people to help her rescue others who’ve disappeared by opening a portal to a different dimension.

Also starring Emory Cohen, Patrick Gibson, Jason Isaacs, Ian Alexander, Phyllis Smith, Brendan Meyer, Brandon Perera, Will Brill, Sharon Van Etten, Scott Wilson, Alice Krieg, and Paz Vega, season 2 of The OA debuted via Netflix this past March.
