In a capsule review for "The New York Times", film critic Vincent Canby refers to them as "more than two dozen very, very old people, billed only as The Witnesses, whom Mr. Beatty interviewed about the Reeds and their long-gone times." He went on to say, "More than anything else in "Reds," these interviews give the film its poignant point of view and separate it from all other romantic adventure films ever made." "The most evocative aspect of the presentation is a documentary enhancement – interviews with a number of venerable 'witnesses,' whose recollections of the period help to set the scene, bridge transitions and preserve a touching human perspective," wrote Gary Arnold of "The Washington Post".
