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.

The movie really just wants to entertain people.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.

It's simply great fun, a winsome film and an occasionally over-the-top luxury fantasy that never flags.
