I get the feeling this reviewer didn't watch the entire movie. We are led to believe this machine was a derivative of PINN but in the end we see it was actually Will. The true humanity of the machine (i.e., Will) is revealed when we see the nanotechnology spread around the world is healing the environment and not intended for global domination by a power hungry AI. This is pretty much the exact opposite of what you write in the review. Did you watch the whole movie?
