Try to make sense of it all, and you’ll develop a stress-based tic. Relax into its weird cocktail of high school sweetness and real-world horrors, and you could have a good time. If you’re into ludicrous narrative twists and charismatic teen actors, you’ll positively enjoy yourself.

The main plot is about sixteen-year-old high schooler Mickey Bolitar (Jaden Michael), who returns to the US to live with his aunt (Constance Zimmer) in his dad’s old New Jersey hometown. The fictional location of Kasselton is your average Twin Peaks mix of toothsome highschoolers and dark, sordid secrets.

Mickey quickly pals up with two loveable Kasselton weirdos – fast-talking nerd Arthur “Spoon” Spindell (Metal Lords’ Adrian Greensmith, this show’s MVP), and Ally Sheedy in The Breakfast Club-type Ema Winslow (Abby Corrigan). It’s a pretty charming set-up filled with regular teen stuff: sports games, homework assignments, first loves and misfit bonding. More effort than usual is made to humanise Queen Bee and Prom King couple Rachel and Troy, and there’s a fresh breeze of self-aware, modern commentary that blows away some of the cobwebs on tired high school movie conventions. 

When a fellow student goes missing, the newly formed gang of besties set about finding her, a project that ties into Mickey’s own search through his father’s past. When he stumbles upon a creepy house that’s the stuff of local legend, things turn a little Stranger Things and the quipping teens are dragged into the story of mysterious Kasselton boogiewoman Bat Lady (The Walking Dead’s Tovah Feldshuh). Add in history teacher Mrs Friedman (Grease’s Didi Conn), sinister “Sunglasses Man”, aforementioned violent attacker “Octoface” and there’s a large cast of walking secret-containers for the eight episodes to smash open. 

What doesn’t sit right is the combination of everyday teen stuff with some very serious themes indeed. We’re not talking Stranger Things-style fantasy horror, but real-world atrocity tastelessly stirred into this cartoony mishmash. Comedy silliness is side by side with a story based in the darkest period in twentieth century history. A teen rom-com meet-cute takes place while an underage girl flees sex trafficking (while dressed in her underwear because cake, people! You can have it and eat it). There’s a discomfiting clash of tones that once again makes you ask, do the programme makers know? Surely they have to know.

We’ve come this far without mentioning an explanation for this series’ identity crisis: it’s adapted from a story by Harlan Coben. Publishing golden goose Coben is the author of eight billion thrillers, all of which have been or are being adapted for TV (mostly at Netflix, but Prime Video has the rights to the Mickey Bolitar character, the spin-off nephew of Coben’s biggest hit Myron Bolitar). Coben’s escapist stories are lurid, larger-than-life and hugely popular. Shelter has the first two in the bag, but will it manage the third?
