It was OK. I don't see why everyone loves it so much. It wasn't very smart or deep or well-directed.

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.

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

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.
