Your blood may run cold, but you now find yourself pinioned to the story.

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.

The tone of this movie is interesting -- the stakes are both dramatic and high, but it's balanced with a lot of fun, tongue and cheek dialogue.

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