Diabolic Ratings & Reviews
FilmWeek (LAist)
Tim Cogshell
It is every bit as chilling as the original The Exorcist.
Los Angeles Times
Sergio Burstein
It is certainly appreciated that, instead of plunging all its night scenes into impenetrable darkness, Phillips has had the good sense to adequately illuminate what he shows us, as if he had nothing to hide. [Full review in Spanish]
Culture Mix
Carla Hay
The horror movie Diabolic has some scenes that drag, and some of the acting isn't very good. However, the story is strong enough to keep viewers interested with plot twists and suspenseful scares.
Certified Forgotten
Matthew Monagle
It may have an outlandish premise, but the execution is solidly by the book, and the film struggles to carve out a space for itself with these two competing ideals.
Spectrum Culture
Joel Copling
Diabolic is an ungodly, shockingly incoherent mess that falls flat even by the standards of empty genre exercise.
Dread Central
Chad Collins
Daniel J. Philips' Diabolic is slow-burn religious horror that eventually finds its monstrous (and gory) footing.
48 Hills
Dennis Harvey
An effective slow-burn horror that takes its time escalating -- but it does get there. I found the character psychology kind of pat, and one late revelation ridiculous. But this is otherwise a decent, sober-sided possession tale.
Sunshine State Cineplex
Alan French
With too many flat characters and not enough creativity, Diabolic misses the mark.
Sarah G Vincent Views
Sarah Vincent
"Diabolic" (2025) is a possession movie with some unexpected, fresh and provocative twists that buries the lead in the print promotions.
Mark Reviews Movies
Mark Dujsik
Diabolic ... at least gets its dumbest idea out of the way almost immediately.
Queer.Horror.Movies.
Joe Lipsett
Diabolic is a mixed bag: some of the acting is extremely dicey and the narrative stumbles badly in the back half, but lead Elizabeth Cullen and the surprisingly bloody last act makes it a soft recommend
AIPT
Nathaniel Muir
Even though the writing is erratic, Cullen is consistently fantastic. Along with being frightened, she is angry and frustrated. Since Emotionally, she has layers, making her much more interesting. The pairing makes for a satisfying watch.
But Why Tho?
Kenneth Seward Jr.
It also features decent cinematography and a strong performance from Elizabeth Cullen. However, the muddled plot, conflicting messaging, and tame jump scares ruin just about everything else.
Bloody Disgusting
Matthew Jackson
It's a film that struggles a bit with its execution, but by the end, it's stuck the landing so thoroughly that you basically forget the flaws are there, leaving you with memories of great scares and some truly brutal kills.
Keith & the Movies
Keith Garlington
A movie that has the right setting and develops the right tone, but that lacks the narrative freshness or genre punch to stand out from the crowd.
Casey's Movie Mania
Casey Chong
Elizabeth Cullen anchors Daniel J. Phillips' atmospheric religious horror.
Mama's Geeky
Tessa Smith
Elizabeth Cullen shines in this indie horror. A bloody, gnarly clash between fundamentalism and a vengeful witch that's flawed but effective.
MovieWeb
Mark Keizer
What Phillips is effectively doing is taking the most interesting parts of Elise's character...and reducing them to fodder for a cheap batch of horror movie scares.
Strong Female Antagonist
Jenn Adams
Rather than a standard possession film, Diabolic works better as a feminist parable about an avenging angel determined to take down a malevolent patriarchy.
Aisle Seat
Mike McGranaghan
Daniel J. Phillips' film has an interesting take on religious horror that it regrettably doesn't follow through on.
