One of the best horror films in recent years had me reeling from just how unforgiving all of it was. Better still, the film was uncommonly interested in a population rarely depicted on-screen, especially in horror movies. In a lot of ways, I was reminded of Natalie Erika James’ masterpiece .

Per Shudder: A former judge must stop an elderly psychopath who employs a child’s puppet to abuse the residents of their shared rest home with deadly consequences.

In out of last year’s Fantastic Fest, we wrote, “For better or worse, is a chamber piece that succeeds in making the audience feel trapped just like its central characters.”

Geoffrey Rush and John Lithgow are exceptional, and Jenny Pen herself is a true star. If it were up to me, Jenny Pen would be up for an Academy Award this awards season. And it’s not just me who is obsessed. Seminal horror writer Stephen King is a huge fan of the film.

In a now-deleted tweet, King wrote, “I watched one of the best movies I’ve seen this year. It’s called , and I urge you to watch it when it appears on Shudder. Geoffrey Rush stars, with John Lithgow as a geriatric psychopath with an evil hand puppet.” Trust the king. Director James Ashcroft, who previously helmed the deeply upsetting , goes all in with . It’s an angry, upsetting, uncompromising horror movie, and it will no doubt haunt you long after it’s over.

What do you think? Do you have any plans to check out The Rule of Jenny Pen. If you’ve already seen the film, let me know what you think over on Twitter @Chadiscollins.
