What network is it on? Is it a cable show? Urban fantasy?...hmmm....
I did start watching a show called Being Human recently. That is really good. (A ghost, werewolf and vampire all live together...it's quite funny and sweet, and a bit dark.)
If you're watching the American version of Being Human (as opposed to the BBC version, which I am not as fond of) - then it comes on right after that show, on SyFy.
It is a Canadian show, and in Canada they are into season 2 or 3 now, I think, but on SyFy they just started airing it so they are in season 1.
