Sarah, John and Derek have been boring me lately. The stuff with Riley last week turned it around, but on a plot-arc level "why are you whining about your lives when Judgement Day is in four years, and hey, shouldn't John be learning some leadership skills?" but I like robots, and what it means to be human, what it means to be other than human stories, so the Catherine Weaver/John Henry stuff has been fascinating me, and tonight just blew it out of the water.
