For those who still prefer films focusing on human relationships, 51 Birch Street is a must see.
By training the spotlight on his own family, Block covers terrain that is off-limits for most filmmakers. He explores a common but often unspoken family dynamic and does so without resorting to hyperbole or sensationalism. In fact, the film is deceptively low key at the outset.
In addition to providing a probing look at one family - and, by extension, every family - Block has also chronicled a very specific period in recent history. I don't know if this was intentional, but unavoidable due to archival content.
Highly recommended.
