I'm starting a new SF topic because I can't get the old one to load completely, and I wanted to say how exciting the season finale of Torchwood was! It was like watching a slam-bang adventure movie compressed into one hour. You see a lot of attempts at that on TV, but mostly they're just "Get ready, we're going to shock you now." Torchwood wrapped up the story line in an acceptably preposterous way and opened the door to the next one. Altogether very satisfying.
