Immaculate: A Gory Thriller Disguised as Religious Dread

The moment Sister Cecilia’s (Sydney Sweeney) water breaks midway through Immaculate, the film’s true nature is revealed. Up until then, director Michael Mohan had been teasing us with atmospheric dread, a slow-burn mystery wrapped in the trappings of a remote Italian convent. But this scene—Cecilia, bloodied and desperate, clutching her rosary like a weapon as she flees through the catacombs—is where Immaculate finally commits to its horror roots. It’s a grim, visceral turning point, one that forces the film to shed its pretenses and embrace what it truly is: a gory, suspense-driven thriller with ambitions of being something deeper.

Immaculate is a film that wants to be many things at once—a psychological horror, a religious mystery, a body-horror spectacle. It borrows heavily from the likes of Rosemary’s Baby, with its themes of divine intervention and sinister conspiracies within a holy institution, while also nodding to giallo films like Suspiria in its use of color-drenched dread and grotesque imagery. The result is a film that feels both familiar and fresh, even if it doesn’t always stick the landing.

Sydney Sweeney, who also produced the film, delivers a performance that anchors Immaculate in earnestness. As Sister Cecilia, she embodies both the quiet devotion of a novice nun and the growing terror of a woman trapped in a nightmare she can’t escape. Her physicality is particularly impressive—whether it’s the way she recoils from the sight of her own vomited-up tooth or the raw desperation in her eyes as she fights for survival, Sweeney sells every moment with conviction. Álvaro Morte, best known for his role in Money Heist, is equally compelling as Father Tedeschi, a character whose quiet intensity masks something far more monstrous. His transformation from seemingly benevolent priest to deranged scientist is one of the film’s most chilling arcs.

The supporting cast, while not as memorable, still brings depth to their roles. Simona Tabasco as Sister Mary and Benedetta Porcaroli as Sister Gwen provide early moments of tension, though their characters fade into the background as Cecilia’s story takes center stage. Giorgio Colangeli as Cardinal Franco Merola and Dora Romano as Mother Superior add layers of intrigue, their motives and allegiances shifting in ways that keep the audience guessing.

Where Immaculate truly shines is in its commitment to body horror. The film’s standout moments—Cecilia vomiting up a tooth, the grotesque fate of Sister Gwen, and the climactic lab inferno—are visceral and unsettling. These scenes are where Mohan’s direction feels most assured, using tight close-ups and stark lighting to heighten the dread. The cinematography, while not groundbreaking, serves its purpose well, creating an oppressive atmosphere that clings to the viewer long after the credits roll.

However, Immaculate’s pacing is a major stumbling block. The first half of the film feels bloated, overstuffed with slow-burn suspense that doesn’t always pay off. Scenes like Cecilia’s nightmares or her discovery of the convent’s oddities—such as an elder nun’s cross-shaped scars—drag when they should propel the narrative forward. The mystery at the heart of the film isn’t deep enough to sustain this pacing, and the eventual revelation of Tedeschi’s genetic experiments feels more convoluted than chilling.

The film’s themes of purity versus corruption are interesting but underdeveloped. Cecilia’s pregnancy is meant to symbolize both divine blessing and twisted science, but the exploration of these ideas never quite coalesces into something profound. The ending, while shocking, lands with a thud rather than a resonance, leaving the audience with more questions about the film’s intentions.

Immaculate isn’t without merit—its gory set pieces are effective, and Sweeney delivers a committed performance—but it’s a horror film that aspires to be smarter and deeper than it ultimately is. It’s a film for fans of atmospheric dread and body horror, those who enjoy the slow burn of suspense but can also appreciate a well-executed jump scare or two. However, viewers looking for a tightly plotted mystery with a satisfying payoff may find themselves disappointed.

In the end, Immaculate is a mixed bag—a film that has moments of genuine terror and intrigue but stumbles in its execution.
