Torchwood reactions

My husband and I just finished Children of Earth, and good gravy, that was something altogether unexpected. Everyone's been so delightful about not spoiling me, so I'll be equally respectful and keep everything behind a cut.

( Discussion and spoilers )

It was a brilliant, thought-provoking, dramatic, and horrifying series.  Just, wow.

ETA: Since I skipped over all of the reaction posts, I'd love to have a few links to your thoughts as well.  :)
