Right now I am watching NCIS, NCIS:LA, and Vegas. I can't wait for the new season of Suits to start in January though, of everything on tv it is by far my favorite.
I'm more of a scifi fan as well but I don't watch it much anymore since Stargate Atlantis was the last good scifi series. I can't stand shows like Revolution that try to pass themselves off as scifi but are so inherently flawed I spend more time pointing out things that are wrong with them than actually watching the show.
