Former judge Stefan Mortensen suffers a stroke in court and is admitted to a rest home, now requiring a wheelchair. While adjusting to his new reality, he meets Dave Crealy, another resident who proves to be a psychopath. Crealy uses a child’s puppet to terrorize and abuse the other residents, with deadly consequences. With no one to help, Stefan decides to take matters into his own hands.

A horror movie featuring a character experiencing something unbelievable, with no one believing or helping them, is not a novel concept. However, applying this premise to a rest home with elderly residents can create a fresh and engaging experience. The Rule of Jenny Pen deviates from the stereotype that elderly people are typically relegated to in horror movies. It still features the challenges that come with aging, but the characters aren’t reduced to just that.

Geoffrey Rush and John Lithgow deliver fantastic performances, convincingly portraying their characters. They are the primary reason to watch this film. The cinematography and soundtrack effectively accentuate the gross, uncomfortable, and claustrophobic atmosphere that the story creates. The film may provoke feelings of exasperation, annoyance, and disturbance in the audience, which is a testament to its effectiveness.

Even with those noteworthy performances, the film fails to explore its full potential. The plot becomes somewhat monotonous and begins to drag, rather than reaching a satisfying conclusion. Trimming the runtime would have significantly benefited the narrative, and introducing character backstories to fill the repetitive moments would have also enhanced the film.

The Rule of Jenny Pen is now in theaters and will be available on Shudder starting March 28, 2025.
