Tied for the best movie I have ever seen

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

Your blood may run cold, but you now find yourself pinioned to the story.

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?
