Sci-fi in the 'post-apocalyptic' genre. Superb visuals and style make for quite exciting heart-pumping action sequences. Good intelligent plotting too, rare for blockbusters nowadays.
Not actually original, but the film combines several clever plot twists at once. It was easy to realize early on that something was wrong, but I didn't quite determine what it was until the reveals. Shades of the 2009 British film 'Moon' there, where the main character was also cloned and operations were being managed by a computer.
Nice final scene. Clever. Thumbs up!
