this be suppose to be a thriller . ok , whatever ... the viewer obviously know that Will Smith will emerge from this harrowing adventure more or less intact , so there really be not any tension create by put he character in peril . therefore , the only tension & suspense the producer of this film can hope to create come from play on the audience 's sense of paranoia . `` oh my god , what if the government really be watch my every word & deed ? '' think the audience . oh my god , this could actually be happen ! all you have to do be read some of the review here and you will see that paranoia be a major factor in this film 's appeal .  all I could think of as I watch this film be , give I a break . one rogue NSA bureaucrat , support by a handfull of computer geek , and they be suppose to be able to conduct a operation this vast ? be you kid I ? have anyone ever hear of information overload ? I do not doubt that a good deal of this technology exist , but let 's get real folk -- if the NSA be really conduct surveillance on this scale , the amount of raw datum the agency would have to sift through simply boggle the mind . the NSA would have to employ half the population of the USA to spy on the other half . if the NSA 's surveillance be this bush-league , most of we could commit all manner of security breach and never get catch ! ironically , I find myself feel more secure about not be scrutinize by the government after have see this film .  as to the film itself -- sure , all the chase scene be grip , the camera angle be great , blah blah blah . the production value in this movie be top-notch , but so what ? Bruckheimer & Tony Scott can do movie like this in they sleep , so it be no big deal . the same can be say for Jon Voight & Gene Hackman , who pretty much phone it in with they role . from a production standpoint , this movie be indistinguishable from the hundred of other so-called thriller that the Hollywood machine have churn out over the last few year . Ho hum . overall , this just really be a thoroughly mediocre film .
