What make Continuum different and interesting, isn't the central plot to the show, it's the characters and their motives. It's a bit more nuanced than your typical good cops vs. bad guys.
The show starts off in a distant but possible future where governments begin to fail to repay their debts and Corporations bail out the governments, to what extent we don't know. You do learn that the government very close with these corporations, and that not everyone enjoys how the corporations are running things.
A group of terrorists are constantly trying to disrupt the corporations and bring them down with any-means necessary, or so we are lead to believe, and this is where the show get's interesting. The terrorist are really just terrorists, but rather they are revolutionaries that are trying to build an honest society without the corruption of the corporations.
As the series unfolds. I like knowing that the core 'good' characters want the world to be a better place and are fighting for what is right, while the other characters each have their motives and their means. They each make their own decisions and don't have simple 'bad guy' motives. In fact several times I found my self rooting for the revolutionaries because heck I don't want a corrupt government in place, and some of the characters when given the option of fighting without violence opt for it.
If you give this show a chance I think it's one of the most compelling scifi shows out there. If you liked Caprica, or Battlestar Galactica you will like this show. The characters are very strong and compelling.
