Defiance

This show ended far too soon. It had so much potential, the show masters were just laying the groundwork for what could have been a great science fiction show...and they cancelled it. Syfy ALWAYS cancels their best shows. And, I'm guessing they do it so they can make another Sharknado or two. You have enough diversity of aliens to cause some really wonderfully chaotic alliances and crazy Shakespearean stories. There was so much that they could have done with the series if they kept it around. And on top of that, you had a love for old music, for covers of older songs, and that added brilliantly to the atmosphere. And then it had a cult following. And that following was growing. So, it was cancelled for another Sharknado movie.
