Quarxx’s All the Gods in the Sky (Tous les dieux du ciel) is not easily categorised, and that’s entirely the point. Sitting somewhere between psychological horror, arthouse drama, and cosmic nightmare, this French genre-bender takes its time and isn’t afraid to make its audience uncomfortable—both emotionally and philosophically.

At the centre of this bruising tale is Simon, a deeply troubled factory worker played with quiet intensity by Jean-Luc Couchard. Isolated on a decaying farmhouse in the French countryside, Simon devotes his life to caring for his sister Estelle (Melanie Gaydos), who was left severely disabled due to a tragic accident during their childhood. The pair exist in a shared purgatory of guilt, silence, and unresolved trauma.

Quarxx delivers a slow punch of a film—one that creeps under your skin not with conventional jump scares, but with mood, decay, and despair. It builds its atmosphere with surgical precision, weaving in splinters of sci-fi, existential dread, and surrealism. Simon’s fixation with extraterrestrial salvation offers a disturbing mirror into his desperation—a hope that something beyond this earth might rescue them from their irreversible reality.

While not all of its experimental swings land perfectly, the film is bolstered by weighty performances and a haunting visual style. The bleak, moldy interiors and ghostly farm exterior evoke a tactile sense of rot, both physical and spiritual. Quarxx makes no effort to handhold the viewer, instead demanding that we wade through the same confusion and torment as Simon himself.

All the Gods in the Sky is certainly not a film for everyone. Its pacing is deliberate, its emotional resonance often brutal, and its genre elements veer from subtle to grotesque. But for those willing to embrace its unsettling tones, there’s something strangely transcendent at its core—a meditation on guilt, disability, and the yearning for escape, whether divine or alien.

The Prognosis:

Though it never fully ascends into the upper tier of arthouse horror, it remains a distinct and memorable piece—an otherworldly prayer whispered from the darkest corners of human suffering.
