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

The biggest problem with this movie is it’s a little better than you think it might be, which somehow makes it worse. As in, it takes itself a bit too seriously, which makes most of the movie feel kind of dull.

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?

Worth seeing just to witness how winsome it is.
