Shadow Of God Review: Redefining Possession in a Chilling Light

The exorcism movie. It’s a subgenre I’ve often felt has sputtered its last rites, each new entry a paler imitation of the last. So, when “Shadow Of God” crossed my path, I approached with caution, yet found myself intrigued by its attempt to breathe unholy life into old bones.

We meet Father Mason Harper, a man already walking a tightrope of faith and fatigue, his spirit frayed by a recent, terrifying ritual. His reluctant journey back to the frost-bitten landscapes of his Alberta hometown isn’t a nostalgic homecoming; it’s a descent into a well of past anguish.

The air immediately thickens with the inexplicable reappearance of his father, Angus, a figure Mason believed long buried. This chilling return isn’t just a family reunion; it’s the ominous overture to a story that promises to dig its fingers into the raw nerves of childhood trauma, intertwined with a truly disquieting supernatural horror.

Ghosts of the Past, Present Tense

Mason’s return to his roots is anything but comforting. Reconnecting with Tanis Green, a childhood friend, brings a fleeting sense of shared history, but their bond is forged in the fires of a shared trauma: survival of the abusive cult spearheaded by Mason’s own father. It’s a setup that speaks to those unsettling homecomings many of us experience, where the geography itself seems to hold onto bad memories.

The film captures this unease well before the truly strange begins. And strange it becomes with Angus’s return. Mason’s disbelief quickly shatters against the reality of his father’s physical, yet deeply altered, presence. This isn’t merely a man back from the dead; Angus is a vessel, animated by an entity whose nature remains unsettlingly ambiguous, steering clear of typical demonic tells and thus ratcheting up Mason’s—and our—apprehension.

This narrative choice, to cloak the possessor in shadow, is a smart one, letting the mystery breathe. Adding another layer of dread, Angus’s old fanatical cult begins to stir, their renewed, violent activities a dark mirror to his resurrection, making it clear that the past is not only unburied but actively clawing its way into the present. Mason is thus trapped, forced to confront the architect of his deepest wounds while battling a growing, insidious spiritual threat.

Portraits of Pain and Power

Mark O’Brien as Father Mason is a compelling anchor. He wears the priest’s exhaustion like a second skin, his eyes reflecting a soul stretched thin by past horrors and present anxieties. It’s a performance that sidesteps histrionics, finding power in the portrayal of a man whose faith is not a shield but a constantly tested burden, his chain-smoking a small, visible act of rebellion against the suffocating piety he once knew.

Opposite him, Shaun Johnston as Angus carries the difficult task of embodying both the tyrannical father and the enigmatic presence within. There are moments where a flicker of something like remorse seems to cross his features, quickly swallowed by an unnerving otherworldly quality, making his character a truly disturbing enigma.

Jacqueline Byers as Tanis provides a necessary grounding presence, a fellow survivor whose strength is quiet yet palpable, though one wishes the script sometimes gave her more agency beyond being Mason’s touchstone.

The film wades deep into the murky waters of religious trauma, a theme that resonates powerfully in an age where many are re-evaluating inherited belief systems and speaking out about the damage wrought by extremism. “Shadow Of God” doesn’t shy away from the psychological scars left by a childhood lived under the shadow of fanaticism.

It questions the very nature of devotion when it becomes twisted into a tool of control, a conversation that feels particularly relevant today. The fraught relationship between Mason and Angus, now further complicated by supernatural interference, forces an exploration of forgiveness, retribution, and the near-impossibility of healing when the abuser literally returns to haunt you.

Sights and Sounds of Unease

Director Michael Peterson demonstrates a keen understanding of how to build atmosphere on what appears to be a modest budget, a hallmark of resourceful independent filmmaking. There are some striking visual choices – a scene bathed in an infernal red light, creating an effective overlay of visages, sticks in the mind, as does a disorienting sequence depicting an “upside-down world” where black becomes white.

These moments showcase a visual flair that punches above its weight, reminding me of how early cult classics often used inventive, low-fi techniques to create lasting iconic imagery. The film blends psychological dread with the more visceral shocks of possession and cult horror, set against the stark, isolating backdrop of the Canadian winter, which itself becomes a character, amplifying the sense of cold desolation.

The sound design contributes significantly to the unease, with a score that often opts for unsettling ambience over telegraphed jump scares. However, there are instances where dialogue clarity becomes a casualty, a common pitfall in independent productions that can, unfortunately, momentarily pull the viewer out of an otherwise immersive experience.

It’s like finding a scratch on a cherished vinyl record; you still love the music, but the imperfection is noted. Peterson also weaves in nods to classic horror, a wink to “Raiders of the Lost Ark” here, a touch of cosmic dread there, generally integrating these influences without letting them overwhelm the film’s own developing identity.

When Heaven Itself Harbors Ill Will

The masterstroke of “Shadow Of God,” and where it truly plants its flag in unconventional territory, is the audacious implication that the entity possessing Angus is not from the infernal pits but from somewhere altogether more… celestial. Yet, this is no benevolent spirit; it’s a force with a terrifying, seemingly misanthropic design for humanity.

This is a bold, gutsy move, one that takes the well-worn tropes of the exorcism film and turns them inside out. It challenges the audience to consider a spiritual conflict far more complex than the usual demons-versus-priests binary. It’s the kind of narrative risk-taking I often champion in independent cinema, a willingness to poke at uncomfortable theological questions.

This “divine” possession elevates the film beyond simple genre fare, prompting a deeper contemplation of religious fanaticism from an unexpected angle. If the divine can be a source of such terror, what does that say about the nature of absolute power itself?

The film’s mythology, drawing from Old Testament severity, apocalyptic visions, and its own unique supernatural rules, is ambitious. While the reveal of the entity’s nature might feel somewhat understated to some, lacking a bombastic crescendo, its quiet horror has a way of lingering.

The narrative wrestles with these grand ideas, and while the execution might sometimes strain against its budgetary seams, its ambition to reframe spiritual horror for a modern audience grappling with fractured faith is commendable. The film’s resolution for Mason is hard-won, offering no easy answers but reflecting a realistic, if bleak, understanding of trauma and the arduous path toward any semblance of peace.

Shadow of God premiered at the Calgary Underground Film Festival in April 2025 and was released digitally on April 11, 2025. It is available for streaming on AMC+, Shudder, Philo, and can be rented or purchased on platforms like Apple TV, Amazon Video, and Fandango at Home.
