Stayed away from spoilers and finally watched this last night. My main issues...
- After she shuts him in her room (he had just found the hazmat suit) he's able to get out almost immediately
- Her throwing the Molotov Cocktail right into the "mouth" of the alien craft (adrenaline could've played a part, but come on man)
- one alien ship was out roaming around their farm at the moment she escaped...yet she's just gonna drive the whole way to Houston without being noticed
It was entertaining for 90 minutes and I'd recommend it to others.
Finally broke down and watched it out of sheer boredom. Never planned on watching it.
All in all I was entertained far more than I was expecting. The tension and mystery of the whole bunker thing was top notch. Honestly could have made a movie just with that scenario and done just fine.
Ending felt a little out there but I actually like how it doesn't really explain anything. Normally that pisses me off but it somehow worked for this.
