Influencer culture should be fertile ground for horror. There’s a delicious potential in stoking our schadenfreude as we watch the vapid and the beautiful get bumped off in inventive ways; alternatively, there’s plenty of scope for a deep-dive on the psychology and sociology of Instagram celebs: what makes them tick, what role do we, the viewer, play in their lives, why do we watch, and why do they want us to? All of that stuff. The problem with Shook is that it attempts both approaches and consequently manages neither.
Mia (Daisye Tutor) is a moderately-successful influencer, sharing the glamorous ticks of her life via make-up tips on an unnamed Instagram-style platform. She has slightly less glamorous, less popular influencer friends, and a decidely unglamorous sister, Nicole (Emily Goss) living with the same degenerative genetic disease that recently killed their mother. Mia is back in the family home, passing up on a boozy sleepover with her ’grammable buddies to dogsit while Nicole is away. When said dog goes missing, a mysterious phone call triggers a series of sinister games, with her friend’s lives apparently at stake.

All of this puts a classy frame around an image that doesn’t really deserve such stylish presentation. Harrington leaves the richer subtext unexplored as her film unsuccessfully treads its line between grim thriller and schlocky slasher. The tone swings wildly between the genuinely unpleasant and the pleasingly fun, both of which have their places in horror but rarely work side-by-side. It’s all such a waste. A witty death early-doors tells us we’re going one way, a self-conscious, super-weird edginess on the other side of the titles suggests we’re going another. Ultra-violent realism gives way to a scene where a character manages to walk without much difficulty on a broken leg. More frustrating is a lack of attention to detail – at one point Mia tries to google something on her phone only to find she has no cellular service, which given that she’s in an extremely techy house that definitely has wi-fi shouldn’t really be an issue, what’s more, the fact that she’s literally talking to someone on the same phone at the same time suggests her service is fine. Were I her, I’d change my provider. Such moments wouldn’t even be noticed if the narrative was more compelling, but a lack of momentum means they stick out like a giraffe in the penguin pool.
