There’s a scene early in Two Night Stand where one of the two leads cannot enter a bar because she forgot her ID. Her forgetfulness is not charming – it’s both gendered and irksome – and the script doubles down on this quirk when she laments, at age 22, she’s “Benjamin Buttoning” toward immaturity. It is unclear whether screenwriter Mark Hammer and director Max Nichols are aware of the joke’s inherent irony, which is frustrating since parts of their film demonstrate a canny understanding of modern hook-ups in a way that few movies do. Many romantic comedies are shy about the particulars of sex. At last, here is one that discusses them openly, even if they’re sandwiched by cringe-worthy contrivances.
