Very very predictable, including the post credit scene !!!

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 acting in this movie is really good.

It is a whirlwind of delight --- attractive actors, stunning couture, spectacular sets and outrageous parties. It's a feast for the eyes. But what really makes this dramedy work is the acting.
