**One Night Only**, the Will Gluck-directed romantic comedy starring Monica Barbaro and Callum Turner, opened in theaters on August 7 with a Tomatometer sitting at 49% from roughly 70-80 reviews. Early critic consensus highlights strong lead chemistry and the stars' committed performances—including on-screen singing—but frequently cites uneven execution, a thin high-concept premise about a single night when premarital sex is legal, and structural weaknesses that keep scores in mixed territory. Pre-release buzz centered on the cast's star power (Barbaro fresh off an Oscar nomination and Turner from BAFTA recognition) and Gluck's track record with crowd-pleasing rom-coms, yet the initial wave of notices has produced no strong upward momentum. Additional reviews arriving in the coming days, plus any late critical reappraisals or audience Popcornmeter movement, remain the key variables that could nudge the final certified score.
