Rarely does a film come along that's as truly adult as Blue Valentine, a movie driven by stunning, lived-in performances from Ryan Gosling and Michelle Williams as a young married couple. In converging timelines, Valentine tracks both their initial courtship and the 48-hour period where it falls apart. The effect is no less emotionally brutal than a film like Gaspar Noé's Irreversible, as each happy memory of the past sweetens the pair's love story--while simultaneously making their falling out all the more devastating. Over a swelling score by Grizzly Bear, director Derek Cianfrance sets about autopsying Gosling and Williams' history, examining each cutting word and each loving gesture as if they were organs from the same body. by Dave Bow
