Disturbing yet enthralling

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

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 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.
