Would have been the latest episode of Castle, but had to give up a few minutes in because the broadcast quality was so bad, inexplicably. Picture kept dropping out and stuttering and there was a bunch of horrid screeching going on in the sound, it was ridiculous. I'll have to catch it online tomorrow.
So instead, watched an oldschool Doctor Who with Tom Baker and Lalla Ward. Good fun, and a lot more science fiction-y than most of the new series.
