Let's take two emotionally unstable alpha males (one of them a psychopath), and have them cross paths leading to a confrontation and tragedy in the desert - and you have quite an intriguing yarn. My main criticism would be that the protagonist was not that likable a character. He was dissatisfied with his glamorous life and rather unkind to most of the people he encountered in the film. I get that there were issues with his wife and child, however, this gets only a brief mention in the movie. Perhaps it should be have been built upon more to make him a more sympathetic character. Yes, rich people have problems, too - we just weren't entirely sure what his were. BUT - he played his role very well and I did enjoy the movie. Kudos to both actors for their performances. It was suspenseful and fairly quick-paced.
