It's entirely possible that sending the audience out feeling lousy was intentional

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.

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.
