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 film of deceptively outspoken contemporary relevance, this is cinema at its most alert, alarming and alive.

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

Ok... Let's be honest. It cannot be the best movie but is quite enjoyable. The movie has the potential to develop a great plot for future movies
