A brilliant film that helped define a genre

Very interesting film. Was caught on the premise when seeing the trailer but unsure as to what the outcome would be for the showing. As it turns out, it was a very good film.

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

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.
