My friend wanted to go back and re-watch all of NuWho since we started watching it together in S7, and she'd missed a couple episodes from previous seasons. So, we've just started over again with "Rose" and have watched the first couple episodes of Nine's run.
God, I'd almost forgotten there was a time when companions were actual human beings instead of plot devices only worth keeping around because there's some "mystery" attached to them. I remember being kind of "meh" about the first half of S1 when I first saw it, but after three years of Moffat's brand of empty expository storytelling, I've come to appreciate the earlier episodes much more.
