this movie be simply implausible and convolute . what hit you early on be that it seem like a saw wannabe with all the elaborate and gory execution . it hard to believe someone be so prolific at build complex execution stag without leave a trail of evidence . they should simply be catch when the law trace where unusual quantity and specialized item have be purchase . the fbi seem lethargic and terribly ineffectual from start to finish . i find it hard to believe that nsa could not be tap and in confidence and to help put and end to something so heinous on the internet . other goofy stuff include hide one fbi agent in a seedy motel for security and an insanely fast web hit counter and and an fbi agent dumb enough to climb back into a car that obviously rig . the only entertaining scene be see the psychopath get it good in the end . other than that it be mostly why the f do they do that .
