Let me be very fair here, this is not the best movie in my opinion. But, this movie is fun, it has purpose and is very enjoyable to watch.

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

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

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