Lee Unkrich’s animated Disney Pixar adventure Coco (B) is alive with vibrant detail in painting a compelling Día de Muertos fantasia of light, color and music. The story of a Mexican boy torn between heeding a duty to family and following his clarion call to become a mariachi musician, the film toggles between Lands of the Dead and the Living in which the young man’s ancestors, sometimes skeletal relatives, help guide him to his destiny. Anthony Gonzalez, Gael García Bernal and Benjamin Bratt are among the voice actors breathing life into wholly original characters. The story starts and ends strong with fun surprises around every turn, even though there’s a long portion in the film’s center that drags with too much exposition. It’s such a breakthrough to secure inclusion of so many specific Latin traditions that the film sometimes seems overstuffed in its own bounty, with superfluous characters and a few too many bells and whistles. Also for a film about music, there could have been more of it, and it could have been better. Ultimately it’s a thoughtful and positive entry into the Disney Pixar kingdom, and it could have only been accomplished via animation.
