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.

A lot of perfectly good film show their cards early, establish a unique premise and let the audience explore a topic at a leisurely pace, without much in terms of surprise. this film is not one of those films.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.
