Nocturne (2020) – A Psychological Horror That Favors Atmosphere Over Frights

Plot, Themes, and Character Development

The film explores themes of jealousy, perfectionism, and the psychological toll of creative pressure, presenting Juliet’s descent into obsession and madness with an almost dreamlike intensity. As she begins to surpass her sister in skill, eerie coincidences and inexplicable events blur the line between talent and dark manipulation.

Acting and Cinematography

The cinematography is one of the film’s greatest strengths, using warm golden hues, dark shadows, and eerie lighting to reflect Juliet’s growing instability. The use of mirrors and reflections subtly reinforces the film’s themes of duality and fractured identity, while the haunting classical score elevates the tension with a melancholic, hypnotic presence.

Directing Style, Strengths, and Weaknesses

Zu Quirke creates a deeply atmospheric and psychological horror that focuses on tension rather than traditional scares. The film owes more to psychological thrillers like Black Swan than supernatural horror, relying on mood, music, and paranoia over jump scares.

Final Verdict & Score: 6/10

Nocturne is a visually striking, slow-burning psychological horror that thrives on atmosphere and character study rather than supernatural spectacle. While Sydney Sweeney’s performance and the eerie cinematography make it an engaging watch, the predictable story and lack of true horror elements prevent it from fully standing out in the genre.
