The film received mostly negative reviews at the time of its release. Critic Paul Brenner stated: "In this badly misconceived pseudo-biography of the legendary Cuban revolutionary—played, incredibly, by Omar Sharif—Che Guevara takes up the cause as a rebel fighter under the direction of Fidel Castro, played—also incredibly—by Jack Palance." "Che!" was listed in the book "The Fifty Worst Films of All Time" (1978). "The Book of Lists" (1977) labeled it "a cardboard, pseudo-historical drama" and noted that "Poor Sharif is forced to deliver lines such as 'The peasant is like a flower, and the revolutionary like a bee. Neither can survive or propagate without the other'".
