Pilot
I thought it was just OK. I think Jo is a great lead and there's no Mary Sue syndrome to where she is over the top badass. Majority of the characters are good, but a few seem unnecessary to where they could've filled in more around with the incident of what happened. However, it seems like a small town and they went with the "family dynamic".
The story is somewhat unclear. The little girl has like zero trauma and cut out a pebble device in her neck...so she has to know something. I was hoping for more information in the Pilot, but we don't really know anything. I know another episode aired, but I only watched the Pilot so far.
