I loved this story, it is EXACTLY my type of metafictional fun. The Story & the Engine is about how humans tell stories to be people, to share culture, to survive (to, in the words of Terry Pratchett, be the place where the falling angel meets the rising ape). It's an episode steeped in Black culture and history - Inua Ellams is Nigerian and god it's so refreshing to have new voices on this show.

It also, and I cannot stress this enough, brought back the Fugitive Doctor for a cameo to state that she had a brief lesbian situationship with Abena, Anansi's daughter

This may well be the best Doctor Who has ever done it
