Advertisements "The Sci-Fi Channel will be showing 'John Doe', another dead series that premiered with cult hit Firefly. It features a man with no memory of who he is but, but somehow has infinite knowledge. With his gift, he solves crimes which are hinted through his monochromatic sight with color. The show will re-premiere Friday, Jan 20 at 9pm ET." It's raining new shows on Sci-Fi, apparently.
