It's hard to see any effort in the film. There's no comedy to speak of, no real drama and, worst of all.

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.

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

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