Diabolic
Chandler Danier
Written on 2/20/2026
I did not know that I found Mormons to be so scarey. I cringed when they said the name Jeffs. Evil makes you do dumb things. That's standard. So when the people do dumb things. It's because of the evil. Great creepy atmosphere. Not necessarily overused baddie but it looks a little terrifiering. Great to see a non-catholic horror. Nice tree shots. Diabolic.

Elise is in a lavender relationship (she's really a lesbian) with her frustrated boyfriend. She's also an ex-member of a nutjob cult. The spirit of a witch has latched onto Elise thanks to her God-bothering brethren and now wants to possess her for all time. It's a rather peculiar story that doesn't really get off the ground. Instead, it offers up moments of genuine creepiness and minor revelations that are not that surprising. By contrast, acting from the lead, Elizabeth Cullen is enthusiastic, committed and borders on excellence. She really carries this rather offbeat film that's not up to the standard of performance she offers up. In summary, Diabolic isn't dreadful, but it's not going to win any accolades in the horror genre either. Its offbeat, rather odd story never really goes anywhere overly interesting, and the scares just don't quite make the grade.

Diabolic (2025) is a masterclass in atmospheric dread that perfectly aligns with the sensibilities of anyone who appreciates the cold, uncompromising nature of extreme black metal. While the film begins with a slow, deliberate build-up, it masterfully transitions into a visceral, gut-wrenching experience that refuses to rely on the hollow comforts of a traditional Hollywood ending. The cinematography captures the isolated, foggy forest setting with a haunting beauty that feels both oppressive and inevitable. Elizabeth Cullen delivers a standout performance that anchors the narrative, ensuring the intensity never falters. It is a rare, bleak piece of horror that stays true to its dark roots, providing the exact kind of nihilistic resolution that feels both earned and chilling. For those who find beauty in the shadows and prioritize an unrelenting, gloomy atmosphere over safe storytelling, this is a must-watch.
