I like these kinds of survival situation movies, but this woman made so many bad decisions it was hard to enjoy it.
First mistake I noticed was her trying to pass the vehicle and choosing to drive faster nearly having a head-on collision with a semi truck. Instead she should have thought hey maybe this isn't a good time to pass. In real life the semi truck would have attempted to brake too, but didn't.
Second thing was not telling anyone at all that she felt she might be being stalked. She had a lot of opportunities to do so.
Like a lot of the other reviews here have said, she kept yelling and giving away where she was.
And lastly who is in a life or death situation and chooses to half of her face covered with her hair the *entire* time, even while she was driving. There's no way she could see out of that one eye.
