It was nice to see TCI, no matter how many times I had already watched it - but not since the new series had started for real, interestingly.
Which meant I noticed how a lot of lines that I didn't pay a lot of attention to at the time seem to have taken on a completely new light. Particularly from Rose.
That, and situations - Torchwood seems very different once you know a bit more about it.
Still love the episode, mind, though the first half seems a lot slower than I originally found it.
