House on Eden

The movie includes "graphic nudity" and depicts "a fully naked older woman with no coverings at all". In a ritualistic scene, Kris's clothing is stripped off by a group of nude cultists around a bonfire. The demon Lilith is described as a "demonic, raven-haired succubus" who "steals the seed of sleeping men". There is also a "close-up shot of Kris' stretch pants-clad backside". Additionally, characters Kris, Celina, and Jay "crudely joke about family incest" while driving.

Parental reviews specifically highlight "profanely foul dialogue". The dialogue is described as "f-word laden... stupefyingly tedious" and is noted as reportedly improvised. One review explicitly states the film is "rated with a hard R with foul language".

The main antagonist is Lilith, a "malevolent, ancient spirit" described as a "dark spirit who pranks men and targets pregnant women". Lilith is also identified as a "demonic, raven-haired succubus" from Jewish folklore. The movie includes "cultish creepiness", "pagan rituals", and climaxes with a "coven surrounding a roaring bonfire". Kris becomes "possessed by Lilith and welcomed into her cult", and Celina also displays "signs of possession". Characters utilize devices such as an "Alice Box" and a "cat ball" to communicate with spirits.

The film is described as "packed with Blair Witch-like thump-in-the-night stuff" and features "nightmarish and, at times, surrealist imagery". Reviewers note an "abundant" number of jump scares, with the first occurring "prior to the one-minute mark". Kris is "knocked down by an unseen force", and later, Celina sleepwalks and "briefly shows signs of possession". Kris is also "isolated and targeted by the supernatural entities multiple times". A scene depicts a possessed Celina with a "nasty wound on her arm with surprise gore and blank, milky-white eyes". The ending involves Kris joining a group of "nude cultists gathered around a massive bonfire" after being possessed.
