Netflix’s new bingeable series Something Very Bad is Going to Happen is exactly what it says on the label: an inescapable feeling of dread spawned by a very creepy family planning a very strange wedding.

Even the happiest of weddings are fraught with potential disaster: a wardrobe malfunction, a catering miscommunication, and the possibility of being jilted at the altar. But in Something Very Bad, which comes from Stranger Things‘ producers The Duffer Brothers, the sense of impending doom has more terrifying manifestations: a strange family in an isolated mansion in the snowy woods, an unknown creep lurking in the wine cellar, abandoned babies, rotting animal corpses, freshly-dug graves (for humans), and an effigy of the bride hanging from a tree near the site of the ceremony, to name but a few.

The premise of the show is simple enough: Rachel Harkin (Camila Morrone) and Nicky Cunningham (Adam DiMarco) are young and in love and once engaged, head to his family’s remote “cabin” for the celebration. (As cabins go, this one is palatial.)

This is a simple enough premise, but everything about Nicky’s family is more than a little off. Nicky’s high-strung sister Portia (Gus Burney) commandeers all the wedding planning, coming to the rescue after Rachel’s dress “mysteriously” disappears. Nicky’s brother Jules (Jeff Wilbusch) and Jules’ wife Nell (Karla Crome) have a dangerous marital dynamic, and Jules’ son Jude (Sawyer Fraser) has soaked up a lot of weird family lore that the show discloses in small spurts throughout the eight-episode series. Nicky’s mom Victoria (Jennifer Jason Leigh) wanders around incoherently at times, and at other times seems to be fixated on Nicky. And his dad Boris (Ted Levine) is really, really into taxidermy.

Something Very Bad is Going to Happen is very good at generating terror at what might happen next, but a horror series needs more than what-ifs to keep the heart pounding. In comparing it to Mike Flanagan’s excellent multi-part Netflix series like The Haunting of Hill House or Midnight Mass, Something Very Bad comes up lacking, and not just in how scary it manages to be.

The Haunting of Hill House, especially, spends a lot of time developing the characters of the family so that when the horror hits, we actually care about what happens to the family we’ve come to know and love. But Something Very Bad, with a sagging middle where very little happens to characters that we don’t know all that well, plays out more like the latter seasons of the Duffer’s more famous series, which seem to drag on forever.

Still, there is a payoff worth waiting for if you stick it out until the end of the series, if you’re willing to coast on vibes only for a few episodes.

The series also stars Amanda Fix, Zlatko Burić, Victoria Pedretti and Josh Hamilton, and was created by Haley Z. Boston (That Brand New Cherry Flavor), who produces along with the Duffer Brothers and Weronika Tofilska, who directed half of the episodes.

Something Very Bad is Going to Happen is currently streaming all eight episodes on Netflix.
