I just watched this movie...
and it's a surprise winner! I'd heard bad things about this film, and went in with low expectations. Not only was it an entertaining romp, but also a lot of fun. the Shaky-Cam is a little over done, but the action is well paced and the acting acceptable.
It could ALMOST be a prequel/invasion of the Falling Skies tv series. (falling skies is set several months after the invasion has been concluded, humans lost)

Reality is a nice place to visit, but i wouldn't want to live there
