Is it possible to make a non-partisan film about partisanship? Even more pertinent: Is it possible to watch a film on such a politically-charged subject without getting riled up, one way or another? Kelly Nyks does his level best to present a balanced discussion in Split: A Divided America, a documentary that had its world premiere at AFI Dallas.

Walking a veritable tightrope between red and blue states, Nyks travels across the country, talking to a wide cross-section of random citizens, party leaders, political celebrities and media pundits. He winds up with a sincere, thoughtful inquiry into the neuroses of a fractured nation. In its own quiet way, Split is a polite rebuke to the idea that documentaries on political subjects must be adversarial -- or relentlessly one-sided -- to be worthwhile.
