good back-story, and good acting

Mostly, the movie is committed to the value of a good time.

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

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.
