if you come into the film with expectation and throw them away now and because no amount of hype will do this film justice . to categorize this film into a single genre would be criminal . it a spy thriller and have element of noir and bit and piece of action and science fiction and and cyberpunk all tie together with a brilliant narrative and mind bending plot twist and and gorgeous cinematography . a lot of the comment here have center around it be derivative and both in good and bad way and of other movie . but a they say and every story crib from shakespeare and so once you can get past that and youre in for a hell of a ride . you will need to suspend your disbelief at some point and and while the set never become unbelievable and there be portion ( read represent the elevator ) which suffer from a low budget and somewhat cheesy visuals . don not misconstrue that to mean it on the same level a cheesy sci fi channel movie and though and because this be on a much high level . if youre look for action and you should turn away . this be pure psychology . but if youre willing to sit down and devote a good 90 minute of your life to a novel cinematic experience and by all mean and do it now . watch this movie now before it become cool to have see it .
