I can see a horror/fantasy channel that utilizes elements of sci-fi but a sci-fi channel should try to keep sci-fi separate from jazz and hip hop. Integrity of the material and the programming standards (discretion) like the pirahnnas and mutant sharks.
Okay, what about ALIEN and its sequels? Heck, most of the classic scifi films of the 1950s had strong horror elements: THE THING, INVASION OF THE BODY SNATCHERS, THEM!, THE FLY, IT! THE TERROR FROM BEYOND SPACE, THE BLOB, etc.
Scifi and horror have been bound at the hip since the days of Mary Shelley and H. G. Wells. What about THE ISLAND OF DOCTOR MOREAU and THE INVISIBLE MAN? Or the blood-sucking Martians in THE WAR OF THE WORLDS or the cannibalistic Morlocks in the THE TIME MACHINE . . . ?
