Leaving aside any wisecracks about Skynet, the Matrix and other robots-will-kill-us scenarios, that was still a bit disturbing. I actually jumped a bit when that hand-bot shot the cord at the ceiling, and its climbing motion looked rather eerie, as pointed out in the article. What's more, the buzzing sound of the eye-bot made my skin crawl; it reminded me of a swarm of angry wasps (which I'm already scared of), only this thing... if it's programmed to find you, it will find you. Also, the creepy background music certainly didn't help.
At least the foot-bot was kind of... cute.
