Very well executed

The story-telling is good with flashbacks.The film is both funny and heartbreaking. You smile in a scene and get a soulcrushing revelation in the next.

The film never slows down or bores, plunging from one harrowing sequence to the next.

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.
