Having watched Elite Squad 1 and 2, and based on its huge success in Brazil, I know José Padilha is a hell of a director... No wonder MGM gave him so many options and freedom. But I think he failed on this one (haven't watched). Too much technology involved, that's not his style. He is a master on the psychological/morality part of the plot, but when the main character is a robot, that's kinda pointless.
I hope the producers are able to at least recover the investment.
