Film critic, David Thomson, describes Deja Vu as "inane yet compelling." I would have to agree. The time travelly stuff expects itself to be taken seriously (unlike the general levity of Back to the Future II); it involves too much disbelief-suspending technology (unlike the natural phenomenon in Frequency); it pervades throughout the movie (unlike the few climactic moments in Harry Potter and the Prisoner of Azkaban); it doesn't involve Keanu Reeves (unlike The Lake House). Oh wait, that's a good thing. The movie is definitely fun to watch, especially during the stylish real time/past time highway chase.
Denzel Washington plays Denzel Washington - charismatic yet slightly rogue officer of the law. The bright lights are Paula Patton and Jim Caviezel aka Jesus Christ. Patton is beautiful, and she manages to be beautiful even when she's scared shitless, rashly daring, and rightfully paranoid. Caviezel, in a tiny villain role, freezes the screen with one, penetrating stare. The hint of arrogance in his voice cements the conviction of his wayward patriot.
