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

Good films always raise compelling questions, whether the format is fiction or documentary fact.

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.

There's a more than satisfactory amount of boom-boom in the movie's trim running time.
