What was just a movie then is quickly becoming reality now. With the erosion of our rights and privacy online, this movie should have served as a harbinger of a world we do not want to live in.
We are introduced to the same arguments politicians, the wealthy and the agencies brought forth after the terror attacks we endured. The exact same rhetoric is used in this film ("if you have nothing to hide..."). At times, it looks like the real world emulates fiction or worse, this film was a blue print.
From a protagonist unaware or unwilling to see the state of affairs, who's unwittingly caught in the path of bad guys, to what might then have been a tinfoil hat wearing, paranoid conspiracy theorist, but would now (post Snowden) be a a very concerned citizen, this film has what it needs to tell a good story.
What's great too is the ending, which is bittersweet. It reflects pretty well what goes on in the highest spheres where the working class has little to no influence.
All in all, a great film for everybody.
