Why so much hype?

The thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;

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

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.
