Even though the tempestuous and truly legendary relationship of Lucille Ball and Desi Arnaz has been covered extensively elsewhere, Amy Poehler leverages a treasure trove of archival footage and taped conversations with the subjects to produce an intensely personal history that comes across as a heartfelt homage to both their dedicated artistry and professional acumen. What really resonates the most is hearing their voices vividly describe episodes of their lives with such candor and a certain wistfulness that still makes their divorce still feel like a tragic inevitability 62 years later. All the more reason to love not only Lucy but Desi as well. It's very clear Amy does.
