Doesn't sound very Hellraiser-ish if it doesn't even belong in sci-fi and fantasy!
(Sorry, that's my bit of mini-moderating over).
Wasn't there talk of a cinematic reboot of the franchise a few years ago? I'm not sure where they'd go with a tv version. Would it be Pinhead hosting a series of anthologies, like the Freddy's Nightmares (Nightmare on Elm Street-derived) show from some years back? How would you make a series based on Pinhead?
