Blue Valentine
A hit at Sundance 2010, this honest and moving portrait of a disintegrating marriage follows Ryan Gosling and Michelle Williams as Dean and Cindy, a married couple who spend a night away from their daughter in an attempt to save their failing marriage. Juxtaposed with moving scenes that trace their romantic courtship six years prior, Gosling and Williams (who was nominated for an Oscar for her performacne) journey through the brutal heartbreak that comes with fading love and broken promises. (Dir. Derek Cianfrance)
