I went mostly for the visuals, which were a bit of a disappointment. If they'd cut every shot in the much-touted "Burly Brawl" sequence where a computer-generated Agent Smith appeared to have the skin tones of a Ken doll, they'd have had a better-paced movie and a cheaper one; likewise for the rubbery cars and trucks in the highway chase.
As to the plot, I've suspended judgment -- "Matrix Reloaded" makes a whole bunch of promises which are left to "Revolutions" to keep, particularly with Neo's new tricks from the last few minutes. What sticks with me, though, is an oddity from earlier on -- for computer programs, Persephone and the Merovingian seem to have remarkably human basic drives. What's up with that?
