It's interesting that the first episode had a grander scale, while the second was more grounded in one area. All around, very very good. Seriously holy crap. So many aliens.
One thing I did find weird is the fact that Rook and Pakmar were around, since it seems everyone else on Mad Ben's world was a human. How did they get there anyway? Really should have probably been Gwen and Pakmar instead. Minor qualm.
