Got to be the most predictable, cliched BS in a long while *spoiler*
Who DIDN'T see the twist coming a mile off? I'd halfway made my mind when the army killed all the adults and no one bothered to ask them how their vehicles were working, then was 99% sure when Maria Bello's character was putting the chips in the kids.
It also fell pretty flat at the end too, no pay off, and Ray Donovan was massively underused in this. Bleh.
