Netflix’s new limited series Sirens isn’t your usual drama. It’s part mystery, part dark comedy, and a whole lot of emotional chaos — all packed into just five episodes. At the center are two sisters, a luxurious island, and a woman who’s as powerful as she is puzzling.
Devon (played by Meghann Fahy) starts to feel uneasy when her younger sister, Simone (Milly Alcock), grows unusually close to her wealthy boss, Michaela Kell (Julianne Moore). Michaela isn’t just rich — she’s famous, glamorous, and deeply involved in causes like animal rescue. But something about her seems... off.
Simone’s connection with Michaela gets intense fast — almost too intense — and Devon shows up hoping to pull her sister out before it’s too late.
Julianne Moore gives an unforgettable performance as Michaela — elegant and mysterious, like she’s always two steps ahead. Milly Alcock holds her own beside Moore, showing off serious range as Simone, who seems torn between loyalty and confusion. And Meghann Fahy keeps it grounded, playing the concerned older sister who’s just trying to figure out what’s really going on.
Sirens blends real-life emotional issues — anxiety, trauma, the power gap between rich and working-class — with strange, almost surreal scenes. One moment it’s a family drama, the next it feels like a psychological thriller. Some viewers love the mix. Others say it feels like two different shows stitched together.
With only five episodes, the series doesn’t have time to explore everything. Michaela’s backstory, Simone’s deeper motives — some of it feels rushed. Still, thanks to the cast and mood, it’s the kind of series that sticks with you after the credits roll.
