“Nocturne” is an elegant and unsettling psychological thriller that delves into the shadows of artistic ambition and the dangers of sibling rivalry. Directed by Zu Quirke in her debut feature, the film is part of the "Welcome to the Blumhouse" series and stands out for its refined and eerie aesthetic, reminiscent of Black Swan, yet with a voice of its own.

The film explores female rivalry in a highly competitive setting, addressing themes of identity, jealousy, and the cost of genius. The atmosphere is cold and composed, with shots as precise and symmetrical as piano keys, and the soundtrack plays as crucial a role in the story as the cursed sheet music that propels Juliet toward her fate.

Of note is the symbolic use of musical elements (such as in the poster, where tears become music notes), highlighting the link between art and suffering, talent and madness. Sydney Sweeney delivers an intense performance, vividly portraying the character’s descent into obsession and paranoia.

“Nocturne” is a subtle thriller—more psychological than frightening—that leaves room for interpretation and reflection on creativity as a form of possession. It’s not a conventional horror film but rather an exercise in psychological tension, ideal for fans of atmospheric, dark-tinged stories.

Recommended for those who enjoy stories about rivalry and the mind, especially in artistic settings.
