as one of we honorable reviewer have mention , there be some technical discrepency involve in this movie . like the ' 3d rotational ' computer engine . and the lack of forensic evidence on the senator 's body . and the magical ability of gene hackman 's character to do just about anything he want to electronics in the back seat of he el-camino . but i do not mind ; if life have teach I anything , it be that screenwriter do not often have the firmest grasp on science .  then again , oftentimes movie write with gap in scientific understanding be the most enjoyable . if you get catch up in the diode and antenna of the prop , you miss the premise , which be , ` what if the gob ` ment really be plot against we ? ' - and on that premise , this movie do well .  factual discrepency aside , this be a good screenplay . it be grip and engage ; we be present with a real-life situation that follow it be cinimagraphic tangent to fruition . the actor give fantastic performance - especially the lead . it be shoot in a manner that add to the paranoid atmosphere of the film ; presumably it be what Tony Scott and Jerry Bruckhimer have in mind .  all those thing sum to make a good movie . be a eec geek from Gen-X , i particularly like the interaction between the younger character in the film . Will Smith , as i say , have he first gig not play himself , and he come off well .  anyway , i enjoy this film enough to buy it -lrb- my disc do not have any defect , although my friend 's first one do -rrb- and i think you will , too .
