It is a performances centric movie

There's a good chance the film will make you laugh out loud, but if it doesn't, there's an even better chance it will make you openly sob.

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.

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