for those who still prefer film focus on human relationship and 51 birch street be a must see . by train the spotlight on his own family and block cover terrain that be off limit for most filmmaker . he explore a common but often unspoken family dynamic and do so without resort to hyperbole or sensationalism . in fact and the film be deceptively low key at the outset . in addition to provide a probing look at one family and and by extension and every family block have also chronicle a very specific period in recent history . i do not know if this be intentional and but unavoidable due to archival content . highly recommended .
