It's fun, it's light, [but] it has a hard time when its tries to get heavy.

Fun premise, good actors, bad writing. This film seemed to have potential at the beginning but it quickly devolves into a trite action film. Ultimately it's very boring.

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

Unshakable, witty and deeply felt, the film will be paying emotional dividends for a long, long time.
