Not great, fail.

<SPOILERS WARNING>

It had potential but was yet another movie ruined by the ever-present, obligatory omnipotent Mary Sue female protagonist that can do everything right, avoid all harm, stitch up an NBC suit and gas mask out of an old shower curtain and some leftover diet soda bottles that is so protective that it allows her to survive an airborne agent that kills everything else.

And then she proceeds to out-wrestle the equivalent of a trained alien attack lion and then single handedly take out a huge alien attack ship that showed up unexpectedly launching lasers and missiles and shit at her simply by using a Molitov cocktail that she just managed to whip up with a few ingredients while hanging out and hiding in the barn for 30 seconds from the alien predator she had just beat up.

But almost all the rest of humanity got wiped out by these Keystone Cop invaders (think Pakleds level intelligence from ST:TNG). Ya see... the key to victory is just to throw the Molitov cocktail in the alien ship's "mouth" duh...dumb ass other humans. Haven't you played any videogames before?

And if you're a Mary Sue, make sure to Up, Up, Down, Down, Left, Right, Left, Right, B, A, Start before you go into battle!

And oh yeah, of course the prepared survivor had to be a white nutjob, psycho, child-molesting(implied) freak of a homegrown terrorist.

Basically a hit piece on the average GLP'r but hey glad you liked it.
