I would rate this a 9 except for one thing. I will get to that later.

This show has some really good action, interaction amongst the family, and some really interesting storylines. I don't normally like sci-fi like this, but I have really enjoyed this series thus far. Except...

Parker Posey. Her character adds nothing to the storyline. Without giving spoilers, I will just say, you will enjoy this series more if you just fast forward through scenes with her. Her character literally adds nothing, and her acting is... not good. They would be better off just pushing her off the ship.
