Chris Pine stars as Sam, a fast-talking salesman in the barter business. I spent most of the running time trying to figure out how his company supposedly makes money, and still have no idea. (It reminded me of the SNL fake ad for "First Citiwide Change Bank" - see below). When his peripatetic music-producer dad dies, he leaves Sam a shaving kit with $150,000 and a note to deliver it to Frankie (Elizabeth Banks), the sister he never knew he had. (Her son belongs to the endless line of precociously profane movie kids.)
Of course, Sam and Frankie first have to meet-cute, not once or twice but three times, followed inevitably by long late-night talks, teasing fights, and, on her unknowing part, a thawing that develops into attraction. Pine and Banks are appealing enough, but the movie wastes several other good actors (Philip Baker Hall, Mark Duplass) in throwaway parts. Michelle Pfeiffer does a creditable job as Sam's mother, who forced her husband to choose between his two families.
