Doctor Who S11 episode 9: It Takes You Away

I haven't yet watched the Doctor Who S11 finale, though I will watch it at some point today. But I thought I'd take a moment to write my thoughts on the previous episode, It Takes You Away. I actually took a whole week (and two viewings) to figure out what to write about this episode!

Please don't mention any spoilers about the finale if you comment on this post, because the comments might be read by people who haven't seen the finale yet, including me.
