Very very predictable, including the post credit scene !!!

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's a movie as timely as it is provocative and amazingly, for much of its running time, it is weirdly funny.

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