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 is a whirlwind of delight --- attractive actors, stunning couture, spectacular sets and outrageous parties.

The movie's not perfect, but it sticks the landing of its message. It was engaging - thrilling at times - and I personally thought it was a great time.

One of the most extraordinary films you will see this year. Take that as you want.
