Porter Springs 4 is a bizarre and sometimes disturbing collage of strange family moments, shot over 20 years on summer vacations. Several generations of the Hills family contribute to this cinematographic delight, providing a history not only of themselves, but of home movie photography and its evolution. Hills' brevity in cutting makes for a tight and beautifully crafted non-narrative work in which storytelling occurs subtly and on many different levels. A hilarious glance into family vacations or a chilling epitaph to a dead sister? You decide.
