There are some life decisions you never expect to be part of the job description, when you sign up for adulthood. Taxes? Sure. Car troubles? Expected. Realizing I am finally at the age where my shoulders make more noise than my speakers? Fine. But nothing prepared me for the emotional marathon of helping my mom move into assisted living. It is one thing to know it is the right choice for her care and safety, and it is another thing entirely to sit across from someone you love and admit, with a knot in your throat, that you cannot do it alone anymore.

What made it harder was pretending I had it all together. There is no handbook for this. I walked into those meetings trying to look like a responsible adult, but inside I was a panicked raccoon rummaging through the trash fire of my emotions. My mom, of course, handled it better than I did. But even in the heaviness, there were little pockets of humor, little reminders that we were still us. Still a family. Still navigating the chaos together, even when the path felt messy.

And strangely, that messy emotional territory ended up mirroring the movie I watched last night.

The Rule of Jenny Pen is a New Zealand psychological horror film from writer-director James Ashcroft, and it wastes no time stripping away the comforting illusion that assisted-living centers are safe, quiet places where nothing truly sinister can happen. At the center of the story is Judge Stefan Mortensen (Geoffrey Rush), a man who once commanded courtrooms with absolute authority but now finds himself weakened, vulnerable and dependent after a debilitating stroke.

The film leans into that loss of power, placing him in a cramped room he must share with a former rugby star named Tony (George Henare). Their dynamic is immediately compelling. These are two men who once lived loud, and forceful lives now reduced to negotiating the space between twin beds and the timing of meal schedules.

But the real source of dread comes from down the hall in the form of Dave Crealy (John Lithgow), a long-term resident whose outwardly gentle demeanor hides something far darker. During the day, Crealy seems harmless enough, a quiet, eccentric man who wanders the facility without attracting much attention. But when night falls, he becomes the puppeteer of terror, wielding a hand puppet named Jenny Pen.

What should be a harmless comfort tool becomes an instrument of psychological torment as Crealy uses Jenny’s singsong voice to intimidate, manipulate and terrify the other residents. The puppet’s presence feels wrong in the best possible horror-movie way. It turns a simple felt toy into a symbol of how easily power can be twisted when no one is paying attention.

What Ashcroft does brilliantly in The Rule of Jenny Pen is refuse to lean on cheap scares. Instead, the horror grows in the quiet moments. The shuffling footsteps in the hallway after lights out. The whispered conversations between residents who are not sure if they are imagining things. The sickening realization that the staff simply does not see, or refuses to see, what is happening. The facility is not evil. It is indifferent, stretched thin, and far too willing to believe that frightened elderly residents are confused rather than endangered.

That indifference becomes its own villain. It leaves these people, already stripped of autonomy and dignity, to fend for themselves against a man who is weaponizing his own unraveling mind. And for someone who just put his mother in one of these centers, this level of horror is downright terrifying.

Rush and Lithgow are powerhouses here. Rush plays Mortensen as a man at war with his own failing body, a former authority figure suddenly forced to rely on others for even the smallest tasks. You can see the humiliation simmering beneath his fear, which gives his performance a brittle edge that makes his vulnerability feel painfully real. Lithgow, meanwhile, is absolutely chilling. He knows exactly how to play a man who is a monster. His almost childlike conversations with Jenny Pen are more unsettling than the puppet’s outbursts.

Chucky and Annabelle do not hold a candle to this puppet. Jenny Pen is not possessed or supernatural. She is simply Crealy’s mechanism for delivering his evil, the tool he uses to express the darkest parts of himself without having to take responsibility for them.

The facility, itself, becomes a character over the course of the film. Dim hallways. Flickering lights. The faint buzz of televisions left on to soothe residents who cannot sleep. The place is sterile, quiet and relentlessly mundane. It is the perfect breeding ground for a kind of fear that does not need supernatural help to feel real. As time progresses, the building feels smaller and more suffocating. Every door that should offer safety becomes a reminder of how easily people can be forgotten.

What surprised me most about the movie was how personal it felt. Not just because I spent the past five years navigating the emotional minefield of my mom’s care, but because the film taps into something universal: the fear of becoming powerless, the terror of being at the mercy of someone else’s bad day or bad intentions. Horror often relies on the fantastical to scare us, but The Rule of Jenny Pen does not need monsters. It just needs people in their flawed, frightened and fractured ways.

I give The Rule of Jenny Pen four out of five stars. It is twisted, smart and haunted. It is far more grounded than your average puppet horror flick. If you are in the mood for horror that is not screaming at you but whispering down the hallway while you try not to wake someone, this is exactly the kind of film I urge my audience to watch.

Just do not watch it right after visiting a loved one at an assisted-living facility. Your emotions may not be able to handle it.
