Cuaron fulfills the promise of futuristic fiction; characters do not wear strange costumes or visit the moon, and the cities are not plastic hallucinations, but look just like today, except tired and shabby.
-Roger EbertFull Review
What I find particularly irksome about it is its pseudo-humanism and its calculating political correctness.
-Andrew SarrisFull Review
It's a wow.
-David EdelsteinFull Review
A superior sci-fi thriller and the best doomsday drama since 28 Days Later.
-Roger MooreFull Review
Cuaron does lowdown takes on high concept better than anyone; no matter what genre he touches, he brings grit and loose-limbed humor along with the hand-held camera jangles.
-Amy BiancolliFull Review
Darkly poetic throughout, the film starts with an explosion and ends drifting in fog with no clear resolution in sight. How brave and oddly satisfying.
