In the US and the UK the film received mostly positive critical notices upon release. Vincent Canby, writing in "The New York Times", called it "stunning ... Mr. Herzog views all the proceedings with fixed detachment. He remains cool. He takes no sides. He may even be slightly amused. Mainly he is a poet who constantly surprises us with unexpected juxtapositions ... This is a splendid and haunting work." In "Time", Richard Schickel opined that "[Herzog does the audience the honor of allowing it to discover the blindnesses and obsessions, the sober lunacies he quietly lays out on the screen. Well acted, most notably by Klaus Kinski in the title role, gloriously photographed by Thomas Mauch, "Aguirre" is, not to put too fine a point on it, a movie that makes a convincing claim to greatness." "Time Out's" Tony Rayns noted, "...each scene and each detail is honed down to its salient features. On this level, the film effectively pre-empts analysis by analysing itself as it proceeds, admitting no ambiguity. Yet at the same time, Herzog's flair for charged explosive imagery has never had freer rein, and the film is rich in oneiric moments."
