Falling Ratings?

So I watched the series premiere of Falling Skies last night and I have no idea where the story can go. The show kept my interest and I might watch watch it again, but I feel kind of lost wondering what the hell could happen next. Like I said yesterday, it starts after the alien invasion and we see the people trying to survive. It was cool with The Walking Dead, but there was so much more at stake. The main character was all alone and he needed to find other humans and find out what happened to him and his family. Falling Skies doesn't have any of that yet. The only thing that they left hanging was how the invasion happened and even then there are kids who sort of talk about it. Obviously, people will get killed along the way and aliens will invade along the way, but I felt like the story was very anti climactic.

The aliens kill people with their laser pointer things, but they have also taken over some of the kids. They have attached these succubus things to their spins causing the kids to follow orders from the aliens. The main character's son is one of these kids so next episode they're going to try to rescue him, but who knows what happens from there. Not sure if this is a good or bad thing for the show. It might be good because it might keep people coming back to find out what happens, but it could be bad because people might not care because there doesn't seem to be anything to care about. I don't know. I will watch a few more episodes and see where it takes us. For now, I say give it a shot. I read that it had 5 million viewers so I'm curious to see if those same viewers return.
