Parents grapple with loss after a school-shooting tragedy in wrenching 'Mass'
The piercing traumas of school shootings, when they've made it into the movies, have seldom carried quite the right tone. "Mass," Fran Kranz's meditative chamber piece, is a sober and wrenching exception. The film is about two sets of parents who meet, cautiously and with still raw wounds, to talk six years after a school shooting that brought their families together.
