The New York Times called it "three hours of naiveté merchandised and marketed with the not-so-innocent vengeance that I associate with religious movements that take leases on places like the Houston Astrodome." Variety wrote that the film was "badly in need of trimming its 170-minutes running time" and that Laughlin sometimes seemed to be "only a visiting guest star, since he does not figure in what seems to be reels of irrelevant school action. It is only when he is on-camera that the picture picks up, a commanding figure whose low-key characterization adds to the brilliance of his performance."

Leonard Maltin's film guide assigned its lowest possible grade of BOMB and called the film "Laughable" until the final massacre scene that rendered its peaceful message "ludicrous." In a retrospective review, Donald Guarisco of AllMovie wrote: "Ultimately, most viewers are likely to be baffled by The Trial of
