First, director/co-writer Robert Kramer's semi-documentary drama "Milestones" offers a kaleidoscopic mix of storylines about the hippies, immigrants, and artists who grapple with the nation's evolving character in the wake of 1960s activism. Scenes of both scripted and improvised power reveal a generation's uneasy adaptation to a time when "settling down" became a popular virtue. Mary Chapelle, Jim Nolfi star. Next, a fictionalized war between American fascists and their radical opponents is depicted in Kramer's "Ice," which fuses didactic rhetoric to cinéma vérité-style thrills in its telling of a guerrilla group's assault on the U.S. government. Kramer, Leo Braudy star. 5 1/3 hrs. total on two discs. Standard; Soundtrack: English.
