**Spa Weekend**, a raunchy comedy released in theaters on August 21, 2026, opened to mixed-to-negative critic response that is shaping early Rotten Tomatoes momentum. Review embargo lift produced scores in the low-to-mid 30s percent range across roughly two dozen reviews, with critics citing formulaic plotting, uneven wit, and underutilized talent from leads Leslie Mann, Isla Fisher, Anna Faris, and Michelle Buteau despite the ensemble’s pedigree. The film’s Metacritic score sits near 32–34, aligning with the “generally unfavorable” verdict and reflecting limited differentiation within the genre. More reviews will continue to post in the coming days, though the initial wave has established a clear downward trajectory; audience Popcornmeter data and word-of-mouth could provide later offsets but rarely reverse critic consensus once it solidifies.
