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.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.

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