If you loved The Exorcist, try The Guardian
A bridge between a film you've already seen and one most people haven't. The Guardian has roughly 40.5× fewer votes than The Exorcist — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by William Friedkin, and they both carry the dread mood tag, and they sit in Drama / Horror territory. If that's the register that drew you to The Exorcist, the second film will land in a comparable space — through a different lens.

What The Guardian is
Darkness falls over a suburban home, a baby's cry echoes, a tree branch creaks, a young nanny's smile appears, a family's life unravels, Friedkin helms a chilling descent.
