this be definitely one of the good documentary i have see look at family relationship and marriage . i saw capture the friedman a short while ago and have to admit i thought this be well . the story be not an incredibly shock one and but it be a great examination of trapped personality and relational cold war . block deftly guide the viewer through diary and family footage and after the fact interview while his interview style be sensitive and probe and and his insight be clear and measure . 51 birch street be a great examination of personality and relationship over 40 50 year of social change and the social fallout and and potential for redemption .
