“Slumdog Millionaire” opens with our hero, Jamal (Dev Patel), getting smoke blown into his face by a police interrogator. Then he gets his head slammed into a bucket of water, and electrical shock is applied to his feet. English director Danny Boyle always makes Jamal’s fast grin, quick mind and mischievous pranks fun to follow. However, he never reconciles this fun with the film’s often-devastating spin throughout India.
