Ever wonder what the girls of Sex and the City might have been like if they'd been friends since toddlerhood? Probably a lot like the appealing friends in The Sisterhood of the Traveling Pants 2, the winsome sequel to the winning 2005 film based, as is this film, on the novels of Ann Brashares. Tibby, Carmen, Bridget, and Lena are the Carrie, et al., of this yarn, which picks up in the girls' lives as they're launching into womanhood, figuring out "how to become ourselves without losing each other." The young women fight heartache and family trouble while seeking adventure in their first year of college and the summer after, and trading off a pair of what must surely be the best-traveled garment in the history of Hollywood. All the young actresses have become more famous since the first film, especially Ugly Betty Emmy winner America Ferrera (Carmen), but also Blake Lively (Bridget), Amber Tamblyn (Tibby), and Alexis Bleidel (Lena). But the film is very much an ensemble piece as all four young stars trade off their piece in the spotlight. Adventures take them to far-flung locales like Rhode Island, New York, and an archeological dig in Turkey, and the adventures and friendship continue across the miles. Above all? The Sisterhood, of course. Tibby, over lunch: "I suck at relationships. I should have been a guy." Lena: "Nah, a guy wouldn't worry about sucking at relationships." And suddenly, sisters, everything seems right in the world.
