If you ever find yourself sitting through an old Sliders episode, we hope it's because you like Jerry O'Connell or enjoy campy, cheap-looking sci-fi in its own merit, not because you're intrigued by the visual possibilities of a premise that sees time travelers routinely visiting strange, exotic universes. Sliders started on Fox and ended on SyFy, but with its routinely awful effects—be it the wormhole used to traverse worlds or various mutant creatures—SyFy is where it should've been all along.
