Boring, long, and too preachy.

I was totally surprised at how great this film.You could feel your paranoia rise as the film went on and as you gradually learned the details of the real situation.

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.
