This movie starts off strong and establishes the female main character as strong and intelligent with great survival instincts. That being said, we are given no backstory to this character, not even a glimpse. Then there's the detective who is comically skeptical of her and labels her a drug addict whose burns are from her getting caught in a meth lab fire. Uh proof? She's in a hospital after all. And the ending. Good God. I'm fine with the ending subverting expectations as long as the setup and story are good along the way. The main character behaves in a way that she simply did not at any other point before the ending. She's shown to be resourceful and willing to do what it takes to survive, yet with a gun in her hand she doesn't shoot her captor? She lets him capture her AGAIN? It's ridiculous.
