I watched the 1st season on SyFy, and again just recently on Blu-ray. It is an impressively well-thought-out production, with some elements that reminded me of the Babylon 5 series. All the acting is 1st rate, good special effects are sprinkled here and there that make it look quite realistc, plot devices move the story along without looking plugged-in, and a tension exists on-screen that makes you want to watch the next episode. There's a lot to like here, and I've seen enough of the 2nd season to say it is shaping up to be as good as the 1st!
