Movie started off good enough, but there were a lot of things that weren't explained. Like why the animals would just Converge on somebody and stand there staring at you. And why is it that the sun is the only one who's had any teeth falling out if there was radiation there would be other people affected. The only character I thought it was realistic was Kevin Bacon's character. That's exactly how people would be in that situation. Then the ending.... don't even get me started.. why that girl wouldn't find her family to let them know that she found a Bunker full of food that they could be safe in and then chooses to watch Friends instead.... in my opinion that's completely unrealistic
