There's a great movie to be made about life during Brazil's vast political unrest in the late 1960s, '70s, and '80s - the chaos, the ideology, the dictatorship. Cao Hamburger's "The Year My Parents Went on Vacation" is the cute version. The film is set in 1970, and most of it is seen through the eyes of a 12-year-old named Mauro (Michel Joelsas). The point of view is limited. Hamburger is only slightly more inquisitive than his little protagonist. So when it comes to why the boy has been anxiously dropped off in a Jewish enclave near Sao Paulo at his grandfather's, the story is egregiously short on historical specifics and long on rabid enthusiasm for that year's World Cup, which, since Pelé was playing, was a great one for Brazil's team.
