Simple and well acted, it has tension enough to knot the stomach.

If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

In truth, there is barely enough story here to make a film.

I really wanted to like this movie. I feel terribly cynical trashing it, and that's why I'm giving it a middling 5. Actually, I'm giving it a 5 because there were some superb performances.
