I find this film fascinating for its subtext. It begins with a San Francisco family torn apart: A father's untimely death and his eldest daughter's demise in some far off part of Europe during the politically charged 1960s.
Left behind are the mother and youngest daughter. When the daughter wants to answer the lingering questions she has about her big sib, she sets out to trace the path that her sister took, and to find out what she could about the events.
Of course, she is cautioned every step of the way, first by her mom, then by her sister's long time beau, who very reluctantly and uncomfortably begins to recount the story of their excursion across the continent and their involvement with the "peace movement," and what he knew about his lover's death.
The "Generation Gap" I refer here is the elder "Baby Boom" daughter, played by Cameron Diaz, and her "do anything" free spirited ways, and her kid sis, portrayed in a very reserved performance by Jordana Brewster, who demonstrates how a few years can make a big difference in how you get treated. Here, seemingly trapped in her existence, she plays the part of a bird trying to find her way out of the cage she has been locked in for her life, and trying to get some answers from a world that seems intent on "protecting" her.
This isn't an action picture. I wouldn't even consider it a road picture, even though it takes place in Amsterdam, Paris and Portugal, beautiful locations all. But it is a psychological drama, about putting people's actions into a context, be it historical or just understandable. If you're born between the late 50s to the mid 70s, this film just might strike an important chord with you.
Wonderful performances from Diaz, Brewster, and Christopher Eccleston as the former boyfiend who plays tour guide to both Europe and his ex's final days.
