The film makes a home in your brain and the only cure is to see it again.

The joyful confection is coated in a sparkly gloss, bright enough to gleam from the darkest, most cynical corners.

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

There are moments that feel comical, some horrific, and some downright inspiring but the tonal shifts hardly matter as the end results come to a film that's perfect for this time.
