"Jarhead" is not a war movie. It's even less of a war movie than "Three Kings," "Apocalypse Now," "The Deer Hunter" or "Full Metal Jacket" (which it most resembles). "Jarhead" is a movie about military indoctrination, conflicting moralities and under British director Sam Mendes' deft direction, it's a poignant statement about the current state of our military and its follies in the deserts of the Middle East.
Based on former Marine Anthony Swofford's book about his experiences in bootcamp, Kuwait and Iraq in the first Gulf War, "Jarhead" nimbly avoids preachy politics, instead focusing on the effect the military, during wartime, has on the mind of the individual. Jake Gyllenhaal, capping off a red-letter year which included an Oscar-worthy performance as Jack Twist in "Brokeback Mountain," embodies Swofford with a bewildered fire in his eyes, a man forever scarred by his actions and lack of action in a war he doesn't fully understand.
