A repeat-viewing brain twister to file along-side millennial puzzle films like Mulholland Drive and Memento, Shane Carruth's Primer unites physics and metaphysics in an ingenious guerrilla reinvention of cinematic science fiction: Its analog-egghead approach may be the freshest thing the genre has seen since 2001.
