One Night Only, the Will Gluck-directed romantic comedy starring Monica Barbaro and Callum Turner, opened in theaters on August 7 to mixed-to-negative reviews that have anchored its Rotten Tomatoes Tomatometer near 48% from 83 critics. Early consensus highlights solid lead chemistry and a timely premise but faults uneven execution and tonal inconsistencies, aligning with Metacritic’s 41 score. As a summer rom-com from the director of Anyone But You, the film faces typical genre scrutiny where audience scores often diverge from critics, yet the current trajectory suggests limited upside absent strong word-of-mouth momentum. More reviews in the coming days could shift the percentage modestly, though historical patterns for similar releases show scores stabilizing quickly after opening weekend.
