The can't-believe-I'm-seeing-it school of shock documentary scores a fresh victory in this vibrant exposé of quad rugby, formerly known as murderball and a sport highly unlikely to be immortalized on a Wheaties box. The camera deposits us in the thick of the carnage as quadriplegics in tricked-out wheelchairs mercilessly slam into each other on the basketball court, sending each other's already diminished bodies hurtling to the floor in a quest for points and prestige. The best special effect, though is the players' own moxie: As they prepare for all-important trip to the 2004 Paralympics in Athens, the fascinating practitioners of the sport make it clear that no smart spectator would dare compare their sissy-shunning activities to the Special Olympics. As one glory-bound combatant defiantly declares, "We're not going for a hug. We're going for a fuckin' gold medal."
