It’s an especially fun movie from a director and cast who are clearly having a good time allowing themselves to let loose.

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

The film never slows down or bores, plunging from one harrowing sequence to the next.
