This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

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.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

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