This story has more twists and turns than a second-rate soap opera.

A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

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