I haven't wanted to neurotically close-read anything this much in ages.

Same here! It's amazing. I'm eager to go back through all five eps so far just to be sure I've captured the second-level nuances (I am a very coarse viewer of television--it takes several passes before I notice stuff). It's the only thing I've torrented in months that I've actually considered burning to CD.

It's as discussable as a Joss Whedon show, and in my book, that is a very significant statement.
