Surprisingly incoherent and boring

It's fun, it's light, [but] it has a hard time when its tries to get heavy.

A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.

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