YOU MAY THINK you have an idea of what Sirens, Netflix's new darkly comedic limited series set in the fictional beach resort town of "Port Haven," is all about. The last few years of television have been chock full of shows centered on Rich People Behaving Badly and Getting Themselves Into Trouble.

Showrunner Molly Smith Metzler, director Nicole Kassell, stars Fahy and Alcock stand by the Netflix series’ unexpected finale: “I hope this is a debate people are having.”

After a chaotic and emotional weekend that shifted dynamics between Simone (Milly Alcock), Devon (Meghann Fahy) and Michaela (Julianne Moore), "Sirens" closed out its finale with a twist ending that didn't see the sisters reunite after all.
