Alfonso Cuarón’s family drama set in a middle class Mexico City neighborhood in the early 1970s, Roma (B), is an elegiac tribute to his family’s real housekeeper who was a steady presence as the family slowly splintered. Told with a sweeping tableaux of intimate and epic moments, photographed in black and white 65 millimeter glory and using rich natural sounds without an underscore to accompany several Spanish language dialects, the film is a roaring technical achievement. Tracking shots of bustling city life, a youth revolt and an ocean vista are among its most stunning. The burden of narrative is carried largely on the shoulders of first-time actress Yaritza Aparicio, and she is marvelously revelatory and relatable. A lot happens and also not very much. There’s a long stretch of cleaning house and talking to the dog. There are multiple sequences of the family children talking but not saying much. But then the protagonist is hoisted into a world of opulent cityscapes, profound joy and grief and even a moment or two of genuine action against the backdrop of rising political unrest and tension. Cuarón beautifully and fully recreates the squalor and splendor of his semi-autobiographical childhood memories with his camera floating through its settings and subjects as if caught up in a dream. The storytelling is spare and lacks dramatic characterizations and fully realized linkages to match the power of the visuals. See it in theatres if you can, but even on Netflix, prepare to behold the panoramas of gorgeous moviemaking.
