It's beautifully animated - the climactic sequence in Earth orbit is breathtaking - and its philosophical digressions are fascinating, if completely bananas.
Philip French, Observer [UK]
It's overlong and, for an animated film, there's too much windy philosophical talk of an ontological kind, dropping the names of Freud and the religious historian Mircea Eliade.
MaryAnn Johanson, Flick Filosopher
A whole lotta WTF folded into a derivative, misogynist, and just plain incoherent mess.
Derek Malcolm, This is London
We are treated to superb city landscapes but so much minor detail that you never know who is doing what to whom, or even why.
Andrew Osmond, SFX Magazine
The script is lousy and laughable. Anime fans may be able to take the talky portentousness, but the ideas are ridiculous.
Chris Michael, Guardian [UK]
We're in a post-9/11 world plagued with terror attacks. Is it an American corporate conspiracy? Or the work of a deity? Cue the obligatory second-half metaphysical blather.
Jennifer Tate, ViewLondon
The cyborgs' epic search for 'His Voice' quickly becomes a little tenuous and ridiculous, pushing the film into maddening and tedious territory.
Ben Mortimer, HeyUGuys
One of the most ambitious and interesting movies of the last few years.
Siobhan Synnot, Scotsman
Terrific-looking action sequences alternate with less terrific expository chat. Despite the natter, it's all mildly baffling.
Stephen Kelly, Total Film
Ambitious, perhaps, but hardly entertaining.
Owen Williams, Empire Magazine
A disappointingly dated and unpowered Manga update.
Anton Bitel, Grolsch Film Works
The blending of 3DCG characters and traditionally drawn backgrounds offers a spectacular hybrid playground in which half-human robots can work through the shifting allegiances and crises of faith that have marked the new millennium.
