Sadly Over-hyped

If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

The film never slows down or bores, plunging from one harrowing sequence to the next.

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.
