Despite only hitting screens this week, Netflix‘s new five-part limited series Sirens has already skyrocketed into the streaming service’s most-watched spot. The Julianne Moore-led dark comedy, which lands somewhere between The White Lotus and Nine Perfect Strangers, has amassed a remarkable following online and nabbed a series of glowing reviews, with the series’ devastating cliffhanger finale raising speculation over a Sirens season two storyline.

What is Sirens About?

From showrunner Molly Smith Metzler, the five-part limited series follows Meghann Fahy’s Devon DeWitt, a down-on-her-luck outcast who finds herself on a downward spiral back in Buffalo, New York. Tasked with caring for her ailing father in her childhood home, Devon is desperate to build a stronger bond with her sister Simone (The Rings of Power‘s Milly Alcock). However, a strange and imbalanced dynamic between Simone and her new boss, Michaela Kell (played by Julianne Moore), threatens to derail the family reunion.

Moore’s enigmatic socialite leads a cultish life of luxury that is ‘like a drug to Simone’, and with Devon deciding that it is time for an intervention, friction occurs. Sirens takes place over the course of one explosive weekend at the Kells’ lavish beach estate, when lines are drawn and awkward encounters dominate.

“This story has a lot of teeth,” Smith Metzler told Tudum. “There are real moments of drama, and it’s going to make people uncomfortable. Operatic is a word I like to use to describe it. It’s a true dark comedy — and it’s got a Greek mythology vibe.”

The limited series comprises five tumultuous episodes, each delivering twists, turns and traumatic retellings, culminating in an explosive finale that leaves the door open for a second season. But will the breakout smash actually return or has Sirens reached its conclusion?

Will There Be a Sirens Season 2?

Unfortunately for fans, Sirens season two appears highly unlikely. Netflix billed the production as a ‘limited series’ rather than an ongoing project and Smith Metzler’s Elemeno Pea, the play that the series is based on, does not have a sequel. Without the necessary source material to pull from, it would be difficult for Netflix to capture the same level of intrigue and mystery.

Moreover, the story does appear to reach a full resolution. While fans online might be dissatisfied with the conclusion, lambasting decisions made and the lack of a full character arc for some key players, the series does arrive at a stifling destination. That being said, the prospect of a second instalment isn’t entirely off the table.

In a recent interview with Variety, showrunner and creator Molly Smith Metzler revealed that while Sirens‘ story is essentially ‘contained’, she is highly interested in working on a continuous series. “I’m really excited to move into an ongoing space,” she said, “and I’m actively thinking about that and looking for what that will be.”

Smith Metzler’s sentiments were echoed by lead actor Meghann Fahy, who hinted at the concept of future stories within the Sirens universe. Speaking with Variety, Fahy explained that she “would love to know what happens to Michaela, where she goes. So I think it’s definitely within the realm of possibility. We didn’t talk about it on set, but I would love to do more.”

Even show production designer John Paino seems on board with the idea of a Sirens season two, telling Town & Country Magazine that: “I think there’s a lot to explore there. I would love to do it with everyone because it was a great experience.”

In the same interview, Australian actor Milly Alcock, who plays Simone in the series, added that they would “love to explore” a season two. “It would just be a different story; I don’t know how it would link, because Simone and Devon’s relationship, we leave it at such a sad . We leave these two women in this beautiful goodbye, so I don’t really know how, if there was to be a second season, how it would kind of go about. But of course, I think that Simone’s such a fascinating person. I’d love to.”

As of now, Sirens season two does not appear to be going ahead. Despite significant interest from cast members and fans, Netflix has not renewed the limited series. This article will be updated as we learn more about the possibility of Sirens season two. All episodes of Sirens season one are now streaming on Netflix.
