Some things I liked some I did not.

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

I am only giving this movie a 1 for the great cast, though I can't imagine what any of them were thinking. This movie was horrible

Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?
