the screenplay never lets us forget that bourne was once an amoral assassin just like the ones who are pursuing him . . . there is never really a true " us " versus " them " .
positive

graced with the kind of social texture and realism that would be foreign in american teen comedies .
positive

watching these two actors play against each other so intensely , but with restraint , is a treat .
positive
