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.

It is both painfully honest and laugh-out-loud funny at the same time.

The film may be flawed, but its message is not.

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