Hours of tedious exposition, wooden acting, cliché-ridden dialogue, poor cinematography. It has not aged well and it surprises me to see such positive reviews, although it is a kind of historical curio as it comes out of old Hollywood with passing nods to cinema vérité. It does serve to highlight what terrible actors some of the most popular American actors of the time were, John Wayne is particularly painful to watch, Robert Mitchum also appears similarly challenged in a role that is anything but challenging.
Avoid.
