Stephen Holden reports on a handful of films that demonstrate the resilient nature of the human spirit at the Human Rights Watch Film Festival for the New York Times: Pete Travis's "Omagh," a docudrama about the impact of terrorism on an Irish family, David Redmon's "punchy documentary critique of globalization," "Mardi Gras: Made in China," Marion Lipschutz and Rose Rosenblatt's "The Education of Shelby Knox," about a spunky teenage girl battling for better sex education in a conservative Texas town, and Margaret Loescher's "Pulled From the Rubble," a daughter's portrait of her father, who is the lone survivor of a terrorist attack on the United Nations headquarters in Baghdad.
