The movie kept me on the edge of my seat. Acting was good. Effects were great. But, the whole time, I couldn’t help but slap myself throughout the movie because the main character (Rachel) kept making the stupidest decisions. These decisions were unrealistic and not something you would do in those particular situations. Everything was good except the story line. They just needed smarter protagonists as she kept making the situation worse and worse for herself to the point where I sided with the villain. Other than that, if you like thrilling exciting car crashes then this is your movie, but if you are also an intellectual who likes their movies to also make sense, then this is not for you.
