What a freaking movie. So many twists and turns. Absolutely intense from start to finish.

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

Story: It's very simple but honestly that is fine.

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?
