Tells a fascinating and unsettling true story, and does so well, without pretending to have all the answers.

It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.

The joyful confection is coated in a sparkly gloss, bright enough to gleam from the darkest, most cynical corners.

This movie tries so hard to be funny, yet it falls flat every time. Just another example of recycled ideas repackaged with women in an attempt to appeal to a certain audience.
