Query: Derivative, undemanding sci-fi yarn

It's watchable and looks pretty, but the viewer is never sure whether to immerse themselves in the (extremely flimsy) plot or to play "spot the rip-off" from Blade Runner, Alien, Total Recall, Hardware etc. It's a mildly amusing couple of hours spent, but I just cannot believe the number of reviewers who've lowered their standards enough to give this 5 stars! C'mon folks, this ain't a classic!
