Terrible acting, screenplay and direction.

The performances transcend the film's tropes, grounding it in characters that feel more complete than this subgenre often produces.

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.
