When David Eick took over this series I thought it's not going to be a successful run. And most of the time Falling Skies just didn't work as well as I hoped. There just was too many variables, and them bringing even more aliens in the play in this season I thought it was going to fail. But somehow they managed to wrap this up with a big explosion, war of the world like scenes and new aliens. So, the question is, how they are going to overdo this season? Are they going to do a Disney ending or give audience real picture of how devastating this invasion has been?
And yes maybe the new alien is the big bad although I like fish heads a bit more as what we saw looked like the goddess from Whedon's Angel.
