Okay, there's beautiful visual, there's decent acting, which get this film those two stars from me. Other than that, you gain absolutely nothing by watching it.

Story is non-existent, pace is slow to death with minimum revelation in any given moment. Actually, up until the end you still know virtually nothing about what happened. Second story also non-existent, just an excuse to show interracial sex, which seems obligatory these days in American films. Dialogs are not badly written, but mostly useless, perhaps due to the non-existent story. An abundant of unexplained things, again, up until the end. Also an abundant of illogical things, one example being: Realizing the gravity (or is it graveness?) of the situation/threat, I'm sure the US government can do more than just... that. I know communication frequency can't get through, but I'm certain you can pre-program drones to fly in and out on autopilot to get a recording of the situation. Action is minimum, as is the horror and thriller.

So, that's it, you watch this film and you don't get anything, really.
