That was excellent, totally excellent. I'm not sure I like the Sontarans' new weakness but I guess they had to have
one.

... that young guy's american accent sounded pretty off to me..
But I loved all the lines in the episode, particularly The Doctor's. But my favorite line was "He is too skinny for words! You give him a hug and you get a paper cut!"
I gotta say, I had low hopes for this series. I'm really glad they're not being met for the most part.
In other news... I'm not waiting on Sci-Fi channel anymore. I have The Poison Sky and The Doctor's Daughter downloaded, the former burning to a DVD right now. I'm glad I got my Media Center PC back, now I can have it do all that crap while I can freely use my mac.
