this be one of the only movie heavily portray computer and technology that do not make I gag and cough . sure there be a few flaw here and liberty take there , but overall , it be awesome and frighteningly realistic -- almost too savvy for a general-audience movie . a lot go into this movie and it show .  as for the guy who be rag on it and could not believe that kind of monitoring could be go on , all I can say be ignorance be bliss . maybe he have not hear about Echelon .
