“Best of Enemies,” a documentary that revisits the 1968 debates between William F. Buckley and Gore Vidal, shows that bullying and name-calling can trump smart conversation even when both participants are card-carrying members of the intelligentsia. The stars may have SAT-caliber vocabularies, but their commentary quickly dissolves into schoolyard retorts that audiences were instantly drawn to. Want to blame someone for the kind of immature banter that dominates time on news networks? Start with these clowns.

This fast-paced effort starts with the Hindenburg crash.
