Metacritic reviews

Clarke and his collaborators have achieved a historical record in and of itself, documenting not just this compelling bond and friendship but also a crucial period in the Black freedom struggle that should serve as a valuable resource for years to come.

The movie does a compelling job laying out how vulnerable this relationship was, given their faith, given Ali’s ascendency in the nation and the Nation.

The montage of footage—New York street scenes in the 1950s, 1960s, the press conferences, speeches, footage of the men getting off airplanes, surrounded by a crush of people, or laughing together, talking together, is mesmerizing. Individually and together, both men “shook up the world.” Blood Brothers shows why.

"Blood Brothers” is worthwhile for the introspective investigation of lives so often, in the public eye, devoid of the tangled humanity that all interpersonal relationships carry.

Blood Brothers explores compelling, often heart-wrenching moments; and if there’s a flaw, it’s in how little time the film devotes to the aftermath of that tragic rift.

Blood Brothers struggles under the weight of its subjects.
