Requires tremendous suspension of disbelief...
... from both - characters and viewers. I'm pretty sure that if they spend more time writing it, something clever could have come out if. Now is just a mediocre and predictable attempt at a Philip K. Dickian type of a story (in a real PKD story you never known what will happen next).
But I liked the cinematography and the mood, so my opinion is net positive, but ultimately it is a forgettable experience.
