Yeah Syfy has shown Doctor Who and some spinoffs before, all edited for commercials. Just edit things out.
How much nudity does it have? Just topless or would we be getting cunt and cock?
I think topless, bare arse, full frontal male though with his hand covering his cock. Are what I can remember. Swearing too. I'm not saying they shouldn't show the original, just that those are the reasons I can think of why they wouldn't.
