Idealism in the public school system got its start here in 1955's Blackboard Jungle, based on the book that convinced America that our kids were not all angels and schools were not built from picket fence perfection. Today, Blackboard Jungle is surprisingly dated and ineffective, as its picture of high school violence and perversity seems quaint in comparison to Columbine-style massacres and Mary Kay Letourneau. Even the firey Sidney Poitier an Vic Morrow, playing the school's punks, seem set to a lower level than we've seen from them in later, mor compelling works.
