I need another good Sci Fi series.?

Caprica got cancelled. Stargate Universe got cancelled. V is on a break right now. Fringe is the only show I've been watching lately. Are there any other good ones I could watch? I've already seen Battlestar Galactica and the other Stargate series. I tried watching Sanctuary but it was TERRIBLE! I don't want stupid shows like that or Buffy the Vampire Slayer. Are there any other good ones like Fringe or Stargate Universe?
