After playing with our expectations, this turns out to be a very different sort of film.

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.

One of the most extraordinary films you will see this year. Take that as you want.

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