The title of this film is a puzzle. If it refers to a war inside the mind of the main character - a jihadi plotting a suicide-murder mission on American soil - then it's totally misleading. This character’s internal battles are long over. He now spends his days and nights methodically scouting out a landscape he intends to blacken, all the while ringfenced from reality by religious fervor. If the title refers to a war inside the Muslim community, then it makes more sense. Either way, The War Within is a compelling portrait of madness, and good enough to be classified as a successful post-9/11 film. It’s thankfully free of bombast and hysteria, and doesn’t bother trying to paint a complex portrait of a movement that is essentially not complex.
