How did this get 7.1?

Rating: 4/10 (26 November 2007)

How on earth does this kind of a film get 7.1 from the respected IMDb? The idea is that the US gov has invented (once again) a machine that can use satellites and surveillance cameras to see everywhere, including inside buildings. The acting is OK and the camera work is good, but I just don't get over those technical stuff, the ever beeping and flashing "computers" that can do everything else but change a light bulb. I do like Denzel Washington as an actor, he has good minimal movements in this film that make it human. There are even a few surprises, even if there are some "I knew it" -scenes. This movie just reminded me too much of Ghost Busters... When I want to see a time travel movie I try to find a comedy, such as Back to the Future. TT
