Director Julia Ducournau’s Alpha is incredibly strange — not for anything it presents, but for how its every narrative and aesthetic decision feels like the wrong one. The tale of a mysterious disease, an overbearing mother, and a vulnerable teenage girl, it unfurls in awkward ways, through an HIV metaphor verging on confounding, and several flailing gestures at prevalent social issues, which feel vestigial in function. With a thundering score that underlines obfuscated drama and convoluted symbolism, it becomes hard to take seriously beyond a point, making for arguably the worst movie in competition at the 2025 Cannes Film Festival.

Alpha isn’t so much scary or unnerving as it is befuddling, which is an enormous step down for Ducournau. Her feature debut Raw, a college cannibalism romp, was half-baked in concept, but viscerally unnerving enough to make a splash. Her body horror follow-up Titane — a film that expresses gender dysphoria through metal — swung hard enough for the fences to earn her the Palme d’Or, Cannes’ top prize. However, with her latest, Ducournau’s fixation with metamorphosis becomes scattered (if not entirely wrong-headed), even though its initial scenes hint at something at least aesthetically alluring.

With its title etched in dried earth, the film’s opening images create a connection between the geological and the biological, comparing cracks in the parched ground to the texture of a human forearm riddled with bruised needle marks. These harsh close ups give way to a gentle, warmly-lit scene between gaunt heroin addict Amin (Tahar Rahim) alongside his five-year-old niece Alpha (Ambrine Trigo Ouaked), who, in her innocence, finds beauty in his tragedy, and connects the dots on his arm in felt pen. Moments later, the film skips to something cold and callous: Alpha, now thirteen (and played by Mélissa Boros), lies passed out at a French house party, as a boy in her class tattoos the initial “A” on her shoulder, with a used needle.

Seeing metal and ink piercing skin up close yields a sickly jolt — it’s classic Ducournau — but from there on out, the director begins playing coy in ways that make Alpha feel self-congratulatory. Conversations with characters off screen, and sudden dream-like turns, begin portending twists that are only “surprising” in that you might not be able to expect them, but they do little to enhance or magnify the drama (or, really, help it focus). Alpha’s mother, played by Golshifteh Farahani, is a doctor who’s long been treating a mysterious disease transmitted by blood, the beginnings of which appear as flashbacks with the aforementioned warm lighting. Back in the more cool-toned, washed out present, she grows concerned for Alpha’s safety and soon gets her tested for the deadly virus with no cure, which makes her an outcast at school while she waits.

These distinctly AIDS-like fears and ostracization eventually give way to a matter-of-fact depiction of the film’s disease: the infected gradually turn into marble husks, practically becoming their own tombs. In theory, there’s a perverse beauty to this premise, but Ducournau seldom centers its conflicting, contradictory emotions with her humdrum depiction of its physical effects.

Alpha’s uncle Amin — still an addict, but promising to kick the habit — comes to live with her and her mother, giving the adolescent an outlet to discuss some of her feelings. She’s likewise a comfort to Amin in moments when the world at large can be cruel, but this mutual recognition of their plight quickly zips by, giving way to a story in which even its central disease simply ceases to matter. Before long, the film gets lost in complicated machinations about the relationship between its two timelines (whose color-coding is completely arbitrary, mind you), getting further and further away from its initial premise until it becomes unrecognizable.

The one minor positive to this pointless meandering is the amount of time (and the variety of different scenes) the movie manages to offer its performers. There’s not much cohesion to be found, but Boros delivers a bravely rankled, physically vulnerable performance, as a teenager in search of affection. Rahim contorts himself physically and emotionally, playing an addict desperately trying to fill a similar void. Farahani, meanwhile, tries to balance looming anxiety with utter exhaustion, until her character breaks under the pressure. However, the movie’s many hints at larger social fabrics — at the homophobia and sexism at the core of people’s fears, or the malformed subplot about the family’s North African roots and questions of assimilation — usually take the form of isolated scenes that, ironically, never blend in.

By the time Alpha lays its cards on the table, it reveals a truly mystifying storytelling approach in retrospect, one that can’t even be labelled an admirable failure. Where the film begins and where it ends up may as well be on different planets, and the space between them is seldom tread with the artistic deftness required to connect so many disparate ideas. The result is a work of heavy, flashy textures, but textures alone — and textures that never seem to fully justify their own existence. Ducournau’s strengths tend to lie in engaging with challenging material, but her latest simply plants the seeds for difficult ideas, only to watch them perish from too great a distance to intervene.
