“Wars today,” we hear early in “October 8,” are fought “not only in battlefields but also on different media outlets. It’s very challenging: the war of the narrative, and sometimes even the war over truth.”
It has become increasingly arduous to determine objective truth in the modern era, particularly on subjects as fraught and ideologically riven as the Middle East. But documentarian Wendy Sachs (“Surge”) narrows her focus, and sets her sights closer to home. She aims, in this passionate and timely documentary, to explore how a culture war has unfolded across U.S. universities since the October 7 Hamas attacks on Israel.
