Last night's score was very reminiscent of BSG's score. I enjoyed it greatly.
I thought the same thing. That orchestra with lots of percussion is signature.
Of course they sound similar, Bear McCreary composed both shows.
Check his site to learn more, he already has his behind the scenes video out for the past episode, would love to get the WD soundtrack when ever he releases it.

Um, duh! I'm pretty sure WeAreTheBorg knew it too.
btw, I've rewatched the episode and I've noticed Carl was wearing the same T-shirt as in the comics when he shot Shane.
