I saw a show called Continuum for on the Syfy channel last night. It is a Canadian made show that apparently premiered in 2012, but this is the first I've heard of it. It is about a group of rebels and a police officer from the future who travel back to present day to stop a terrorist attack that killed thousands.
I've heard of the show, a few of my friends rave about Continuum, but I've never watched it. For some reason shows about people from the future coming to our present day bores me. I'm usually all over a good sci-fi, but the premise just didn't do it for me.
