Although it has its amusing moments, in eneral the plot does not convince.

All that we are seeing on the screen is happening with real people, real action sequences in the background, forcing the eye to watch as if we were there.

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.
