There are two types of haunted houses in horror movies: the ones where the walls bleed, the beds levitate, and the priest runs out clutching his rosary like it’s on fire—and then there’s this one, where the big scare is a girl hanging out with a statue. Yes, El Libro de piedra (The Book of Stone) manages to stretch 100 minutes out of the question: “Is this kid just lonely, or is her imaginary friend actually a supernatural sociopath carved out of granite?” Spoiler: you’ll be checking your watch long before you get your answer.
Rock Hard Horror
The premise sounds promising on paper: Julia, a governess with more patience than any human deserves, is hired to care for Sylvia, a rich little girl with a vacant father, a stepmother who looks permanently one Valium away from passing out, and—oh yes—an invisible pal named Hugo. Except Hugo isn’t really invisible. He’s a statue. A rock. A literal slab of boy carved with all the menace of a garden gnome.
Dad shrugs it all off, muttering about Sylvia’s “mental illness,” which is convenient shorthand for, “I don’t want to deal with my daughter, please take her outside before she starts humming the soundtrack from Rosemary’s Baby.” Meanwhile, Julia—our audience surrogate—keeps running into the same problem: either this girl really has a bestie made of limestone, or she’s gaslighting the entire household harder than a Netflix true crime documentary.
Cue the Gothic… and the Yawns
Taboada’s direction leans hard into fog, moody music, and that slow-burn vibe critics love to label “psychological horror.” But psychological horror only works if the psychology is interesting. Instead, we get long conversations about geography lessons, weird lizards, and the family drama equivalent of watching paint dry on a mausoleum.
For tension, there’s a dog that randomly attacks, then drops dead after Sylvia whispers sweet nothings to her rock boyfriend. There’s also a doll with needles sticking out of it, because no spooky movie is complete without a touch of voodoo you could buy at a Halloween store clearance rack. Every time it seems like something might actually happen, the movie hits the brakes and drags you back into its swamp of expository dialogue.
Hugo: The Worst Imaginary Friend Since Drop Dead Fred
Here’s the thing: Hugo is supposed to be terrifying. Sylvia insists he’s real, her dad insists she’s crazy, and Julia keeps playing referee. But when the camera finally lingers on this “evil” statue, you’re less scared and more… bemused. The kid looks like he should be guarding a library fountain, not orchestrating black magic rituals. He’s holding a book, sure, but he doesn’t read from it—he just sits there like a petrified hall monitor, waiting for someone else to do all the heavy lifting.
This is the villain that terrified Mexican audiences in the ’60s? Folks, if your movie monster can be taken out with a Home Depot sledgehammer, maybe you need to rethink your script.
Family Drama with a Side of Pseudoscience
Most of the runtime is spent watching the stepmother whine about “feeling threatened by something sinister,” while the father refuses to believe in anything that isn’t a stiff drink and denial. Every character is convinced Sylvia is sick, possessed, or a budding Charles Manson in pigtails, but nobody seems particularly proactive about it.
The script also throws in half-baked lessons about salt, black magic, and reincarnation that sound less like horror mythology and more like your uncle’s conspiracy rant after three tequila shots. By the time Hugo’s tragic backstory as the child of a sorcerer is dropped, you’ll be too numb to care.
The Climax: Rock On, Rock Off
Eventually, the tension “builds” to Dad finally grabbing a hammer and beating the crap out of Hugo like he’s smashing open a piñata. Naturally, this doesn’t end well. The stepmother dies screaming, Carlos the godfather dies in a car crash (thanks, ghost statue Uber driver), and Sylvia—poor, sweet Sylvia—gets the ultimate punishment: turning into a statue herself. Nothing says “happily never after” like becoming your imaginary friend’s granite understudy.
It’s supposed to be haunting. Instead, it feels like the kind of ending a stoned film student would pitch at 3 a.m. while trying to sound deep: “What if… she was stone… all along, man?”
Final Thoughts: Pebbles and Bored
El Libro de piedra gets praised in some circles as a “masterpiece of Mexican horror” because it doesn’t rely on gore or cheap effects. Fair enough—but let’s be honest: sometimes a little gore, a little chaos, a little something actually happening goes a long way. This is less The Exorcist and more like sitting through a haunted geology lecture.
There are sparks of atmosphere here—fog-shrouded lakes, whispered threats, the uncanny innocence of Sylvia—but it’s buried under so much sluggish pacing and melodrama that you’d think the film itself had been turned to stone. Hugo may hold a book, but watching this movie feels like being assigned the world’s most boring reading list by a substitute teacher who smells faintly of dust and regret.
Rating:
Two petrified lizards out of five. Watch it if you’re fascinated by statues, psychological horror with all the psychology of a fortune cookie, or if you just want to see what happens when a movie literally turns its own heroine into a lawn ornament. Everyone else? Walk past this one like it’s another tacky tourist trap, and keep moving.
