**Mixed critical reception has anchored trader sentiment around a sub-50% Tomatometer for the new romantic comedy One Night Only.** The Will Gluck-directed film, starring Monica Barbaro and Callum Turner, premiered August 3 and hit wide release today, drawing reviews that praise the stars’ chemistry and the timely premise of a single night of legal premarital sex, yet criticize uneven execution and familiar rom-com tropes. With roughly 70–80 reviews logged, the score sits near 48–49% and a Metacritic of 41, reflecting limited precursor buzz and competition from stronger summer titles. Additional reviews could still arrive, but the current consensus suggests the market-implied odds favor a final score in the low-to-mid 40s to low 50s unless late positive notices shift momentum.
