There’s a special place in hell for films that bait you with a killer premise, deliver on the gore, and then torch all goodwill with a plot twist so stupid it makes M. Night Shyamalan look like Tolstoy. That’s High Tension (or Haute Tension, if you want to sound fancy while admitting you just wasted 90 minutes). Alexandre Aja’s film promised a lean, mean French slasher—brutality in the New Extremity vein—and instead served up a cinematic migraine that asks: What if the killer was in your head all along? And by “head,” I mean the writer’s, because this script is a crime.
The Setup: Textbook Slasher
Marie (Cécile de France) and Alex (Maïwenn) head to Alex’s family farmhouse for a quiet weekend of studying. Which, in horror film logic, is basically the same as painting “MURDER US” across the door in pig’s blood. That night, a hulking stranger (Philippe Nahon) arrives, kills Alex’s dad with a bookcase (yes, a bookcase—furniture as weapon, very IKEA chic), slits throats, and hauls Alex off like discounted luggage. Marie, the dutiful best friend, grabs a knife, sneaks into the killer’s truck, and begins her blood-soaked crusade.
On the surface, this feels like standard slasher stuff: remote setting, escalating carnage, and a “final girl” with grit. The first half is tense, mean, and unrelenting. So far, so good. But then Aja decides to get clever. And that’s when the whole film faceplants into its own entrails.
The Twist: Scooby-Doo Logic with Extra Gore
Ready for the reveal? Strap in: Marie is the killer. Yes, that’s right. The entire time we thought she was hiding under beds, sneaking into trucks, and watching the killer commit murder, it was actually her doing all of it. Marie is not only battling a psychotic farmer—she is the psychotic farmer. Because nothing screams airtight storytelling like retroactively destroying your own continuity.
So when Marie was cowering under the bed as the killer searched the room… she was also the killer? When she was in the gas station watching the clerk get axed, security footage shows her swinging the blade. Meaning the film expects us to believe she was simultaneously hiding and butchering people, a sort of murderous Schrödinger’s Cat.
It’s less Fight Club and more Looney Tunes. The audience doesn’t gasp at the twist—they roll their eyes so hard they sprain an optic nerve.
Characters: Paper-Thin and Blood-Soaked
-
Marie: Cécile de France gives it her all, running around in a tank top, sweaty, bruised, and screaming like she’s auditioning for a Cirque du Soleil production of Texas Chainsaw. She deserves better than this script.
-
Alex: Exists mainly to scream, get tied up, and then scream some more. By the finale, she’s so hysterical that you start rooting for the concrete saw just for a little peace and quiet.
-
The Killer / Marie’s alter ego: Played with greasy menace by Philippe Nahon, until you realize he’s essentially Marie’s Fight Club cosplay. At which point, he becomes a hallucinated plot device in overalls.
Gore Galore: Where the Film Almost Works
I’ll give credit where it’s due: the violence in High Tension is unapologetically brutal. Heads are crushed, throats slashed, and intestines spilled with lovingly grotesque detail. Aja knows how to stage carnage. The gas station sequence, the mother’s death, and the barbed-wire bludgeoning are nasty in that way horror fans secretly crave.
But gore without logic is just noise. It’s like someone blasting death metal at a funeral: sure, it’s intense, but it also makes no goddamn sense. By the third act, the buckets of blood feel less like horror and more like a magician waving shiny objects so you don’t notice the script vomiting in the corner.
Pacing: All Gas, No Brains
At 91 minutes, the movie sprints from kill to kill like it’s late for a parole hearing. That should be good—no filler, just carnage. But when every scene is shot with grim seriousness and then undermined by the twist, the pacing feels pointless. It’s like watching someone sprint headfirst into a wall for an hour and a half. Entertaining at first, then tragic, then just exhausting.
Dark Humor Highlights
-
The dad gets his head shoved between staircase spindles and crushed with a bookcase. Forget Jason Voorhees—this is the IKEA Serial Killer.
-
Marie hides under a bed while “the killer” lurks inches away. Except, reminder: she is the killer. Which means she’s hiding from herself. Peak horror or peak farce? You decide.
-
Alex slashing Marie with a knife while sobbing, “You butchered my family!” finally voices what every viewer has been screaming at the TV since the twist reveal.
The New Extremity Problem
Critics lump High Tension into the New Extremity movement—European horror films obsessed with pushing boundaries of sex, violence, and psychological collapse. That’s fine when it produces movies like Martyrs or Inside that marry gore with existential dread. But here? It’s just an excuse to show blood-slick concrete saws and call it “art.” It’s extremity without depth—shock value without substance.
The Ending: Freud Rolls in His Grave
The climax turns into a psychosexual fever dream: Marie, obsessed with Alex, demands she say “I love you” while brandishing a concrete saw. Nothing says romance like industrial equipment and a fresh stab wound. When Alex finally shoves a crowbar through Marie’s chest, it’s less catharsis and more mercy killing—for the audience.
Then we cut to Marie in a psych ward, reaching out at Alex behind a one-way mirror. It’s supposed to be haunting. Instead, it’s the cinematic equivalent of a Scooby-Doo villain growling, “And I would have gotten away with it too, if it weren’t for my pesky lesbian crush!”
Final Verdict
High Tension could have been a sleek, terrifying slasher—a back-to-basics bloodbath that put French horror on the map. Instead, it shoots itself in the foot with a twist so nonsensical it undoes its own best moments. It’s violent, yes. It’s bloody, absolutely. But scary? Only if you’re afraid of bad writing.
Cécile de France throws herself into the role with conviction, the kills are staged with stomach-churning flair, and yet the whole movie collapses under the weight of its own smug cleverness. It doesn’t just insult the audience’s intelligence—it bludgeons it with a barbed-wire fence post.
