If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

Fanciful, disturbing, and wildly original, it announces the arrival of a fresh, bold voice in American cinema.

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

This is a coming of age storyline that you've seen in one form or another for decades. It takes a truly unique voice to make yet another one worth watching.
