The creators of the brilliant French documentary Shoah courageously assume that their audience is willing to sit through 570 minutes' worth of interviews and little else. As unpromising as this sounds, rest assured that you will sit and listen. Relentless "inquisitor" Claude Lanzmann probes the memories of several survivors of the Holocaust--as well as several ex-Nazis who helped perpetrate the horrors. Gradually, one becomes aware that what happened in Germany and occupied Europe in the years 1933 through 1945 was not as "unthinkable" as it may seem to modern viewers; the recollections of those directly involved demonstrate all too well that it can happen anywhere at any time. One review of Shoah has carped that "it really could have been a bit shorter." No, it couldn't.
