[SEVEN NIGHTS ONLY] In 2008, David McKay and Bradley Crowder went to St. Paul, Minn., with a vague idea of disrupting the Republican National Convention and came out—in the eyes of the federal government, at least—as terrorists. How that happened is the focus of Kelly Duane de la Vega and Katie Galloway's engrossing documentary, but there's a larger question involved in this story: Was it nature or nurture? Were these bright, impressionable idealists from the Bushes' ancestral homeland of Midland, Texas, predisposed to making Molotov cocktails they allegedly planned on using against Republican delegates, or were they coerced into it by a former self-described “revolutionary” turned undercover informant? Although it certainly leans in one direction, Better This World doesn't pretend to reach a concrete conclusion, but it does suggest that the definition of justice in post-9/11 America is flexible at best. From a pure story standpoint, de la Vega and Galloway play it out like a tense legal thriller that tests the bounds of friendship and loyalty, and ends with a punchline that gives the entire saga a tint of the surreal.
