Opens as 'The Six-Million Dollar Man', or Robocop with Dock Ock's tentacles, evolves into Her and Ex Machina A.I. scares, then blasts off into the premise of one groundbreaking 1999 sci-fi - because the virtual world narcotic is less painful than the real world. As the action scenes passed by, I went from "maybe an 'upgrade' isn't too bad after all", to "... maybe an upgrade is really bad." Writer/director Whannell uses the same structure he wrote into Saw, flashing us back through the entire film for the surprise ending. We decide whether to stay awake afterward, or go to sleep.
