I agree there is technology that can track, electronic eavesdropping and such. This movie however was beyond just tracking the movements of a person over a period of weeks or even hours. The plot assumed a computer not only can track a person in real time, but calculate the physics of objects falling on the person and hit the person while in transit at will.
For example a guy was walking under high voltage lines in the middle of a vacant filed miles from anywhere. The computer then calculated a amount of current to surge the high voltage lines causing them to rupture and land exactly right on top of the guy as he was walking. The computer did these sort of things one after another, until you just had to laugh at the screenwriters for their lack of knowledge of the reality the real world events are really not that predictable.
Weather, tornado’s are a good example, most life events are random and are subject to chaos theory where a small change to the boundaries can produce a large unpredictable event some time later, no amount of calculations can predict every movement in the universe to exact certainty.
Take planetary motion for example, two planets by Kepler’s laws and gravitation we can plot their positions from now until eternity. But add just a one more planet, and the solution is extremely more complected..
The viewer of this movie is supposed to believe that a computer can be made powerful enough to predict the movement of people and every object on the face of the earth!
As I said, you have to have a willing suspension of disbelief to get beyond that, but once you did, the bad acting and casting, made it unbearable. I have to admit, I walked out on the last 10 minutes, the plot was beginning to be just too predictable, maybe there was a twist ending, so I may not have given a good review it deserves. If you see it, report back and let us know what you think!
I hear you, sounds like they went a bit too far. Sad part is some will think it is possible.
