It's no definitive masterpiece but it's damn close.

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.

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?

One of the best movies of the year! Incredible from the beginning to the end.
