You've not seen Koyaanisqatsi, have you?
It sounds like it's about precisely what the précis says. Those faces staring at you in the trailer, did you not feel some elemental kinship and recognition? A blurring of self and other? A feeling of spiralling around some locus of presque vu, almost seeing? The film will be more of the same, but with our reactions to technology involved.
Anyway, enough silly words.
Edit: Actually no, not enough.
I'd also like to say that watching the people in the trailer watching you back was hypnotic. It was trance-inducing. But they aren't watching you. They're watching something else. Media of some kind, perhaps. Something technological. And they're in a trance, too.
