The first of two sequels to The Matrix released in 2003, courtesy of the original writer-directors, the Wachowski brothers, who have amplified the camp elements of the originalincluding the ultrasolemn performances of Keanu Reeves, Laurence Fishburne, and Carrie-Anne Mosswhile retreading the same metaphysical conceits. Lines like We’re all here to do what we’re here to do reverberate more than long enough for us to ponder their full profundity, and the martial arts choreography is neither graceful nor excitingit’s worthy of a video game.
