Though it features few recognisable faces, this Oz-shot, US-set indie horror displays a core competency that gets it some of the way to where it’s heading – only to collapse, come the final reels, into the usual hacky manoeuvres. Ten years after fleeing a fundamentalist branch of the Latter-Day Saints, snub-nosed artist heroine Elise (Elizabeth Cullen) has started shunning the advances of boyfriend Adam (John Kim), instead obsessively digging holes in the couple’s back garden and trashing the living room in the middle of the night. (You don’t want to see what she does to a neighbour’s poor dog.) Could it have something to do with the grimy cellar door she feels compelled to paint, or the traumatic baptism we witness in a pre-title sequence? What are the chances?
For somewhere between half and two-thirds of its running time, we’re watching a diagnostic case study. Elise and close pals return to Mormon country – more specifically, the in-no-way ironically named hamlet of Haventon – to undergo a regression therapy involving a local ayahuasca variant; this will strike rational onlookers as ill-advised even before an actual cellar door is uncovered outside the venue and everybody starts throwing up. (Cue the especially dreadful line: “She must have torn internally.”) Thereafter, flashbacks reveal what’s been suppressed or concealed: the younger Elise’s growing closeness to bishop’s daughter Clara (Luca Sardelis) would seem to indicate our girl isn’t possessed, merely bi.
The results prove middling at best, hardly the KO religious conversion therapy deserves and never the campy scream this set-up might have licensed. Cinematographer Michael Tessari gives matters a wintry, low-lit, persuasively un-Australian look, and gathers the odd suggestive image, like a dream sequence scattering of petals. More of that delicacy would have done Diabolic a world of good, but co-writer/director Daniel J. Phillips heads the other way, cranking up the soundtrack’s parping and the underlying Mormonphobia: supporting players go decidedly heavy on the repression and hysteria. Seasoned soap fans will spot Dennis Coard, formerly Pippa Ross’s foursquare second husband Michael on Home and Away, among the church elders. Never mind Elise, what’s got into him?
Diabolic is available to rent via Prime Video and other digital platforms from Monday 25.
