Don't know if it's just me, but I find it much harder to be fanficcy in a world where tv is not episodic.

So many shows used to be single episodes each with their own plotline (and an overarching narrative somewhere in the background), and I found it left so much scope for my brain to be fannish. Whereas, when a tv show is basically a 16-hour movie in disguise, my brain doesn't find it as fanficcable.
