Nancy Savoca’s True Love was an early high-water mark in the modern independent film movement. In fact, its storyline, newcomer casting and loose style is now the template for much current indie drama. So, it’s great to report that over 20 years later Savoca is back with another intimate drama realized on a low budget and entirely outside the industry. With a stellar cast (Mira Sorvino, Tammy Blanchard and Patti Lupone), Savoca explores sister dynamics through the lens of a Canon 5D. (Scott Macaulay)
