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.

Although I seem to have had higher expectations than I thought, the movie is super entertaining.

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

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