Yeah, one of my favourite shows of the season as well. Now that Ryll mentioned it, he's absolutely correct about the characters. They all possess some depth.

I was somewhat sorry to see the one thing I didn't want to see in this episode: That only sword swings can destroy the enemy. A nuke apparently didn't do anything apart from stalling it a bit. I'd have rather heard it's extreme difficult to defeat them (very few would be willing to rely on nukes before all hope is lost in any case). I hope this will play no further role in the show.
