We used to have Space Channel, up here in Canadia. It was basically Sci Fi as it was intended to be. Which means Farscape reruns, all the Star Trek series, the Tales from the Crypt HBO series and all the horribly bad flicks you'd watch as guilty pleasures around 2 or 3 AM. Science Fiction exploitation material or just, y'know, Ed Wood's filmography. Around each holiday, they'd pull out a little week-long special of thematic movies or shows. Halloween was obviously the best.
Plus, they more or less kept the whole "horror host" tradition alive, just with more nerdy quips and less slinky dames in Goth outfits.
Does that still exist? I can't find it in my cable provider's listing. If that still exists in that form, I'm sure as shit pushing to subscribe to it again.
As for SyFy - yeah. This screams of New Management and of someone just going "Fuck them nerds, I'm out to make some dinero! Let's option Wrestlemania and buy or produce a fuckton of shitty ghost-hunting shows!"
As a whole, though, I have to agree with everyone else in that specialty channels are losing their edge. The only way they can survive is by turning into a turgid morass of whatever focus groups decide people want to see. Even National Geographic - Freaking NatGeo, one of the most respected print institutions - is letting its TV cousin turn into "Derp, let's talk about aliens, conspiracy theories, vampires and Atlantis for the 32rd time!"
